SH T 1 – CPU
This sheet shows the syste CPU and associated circuitry. IC4 is a Cirrus EP9307 ARM CPU. The
IC runs fro a 1.8V core supply (VCCCORE) and a 3.3V I/O supply (VCCIO).
IC2 is a 64Mbit flash e ory for progra and data storage. IC1 and IC3 are SDRAM e ory,
these run at 100MHz clock speed.
IC6 is a reset generator that onitors both the core and I/O supply rails and keeps the CPU in reset
until both supplies are stable.
IC14 is a 14.7456MHz oscillator odule. This clock is used by the CPU IC which features several
internal phase locked loops to generate the various clocks required; the 100MHz SDRAM clock for
exa ple.
IC5 is a real ti e clock (RTC) IC that provides a 32kHz clock used by the ARM CPU. Note that we
do not currently ake use of the RTC function, it is there only to provide the 32kHz clock for the
CPU. This is an i portant clock and the CPU will not boot without it.
Provision has been ade to use a back up battery for the RTC. Were this to be used, it would
connect to PL10 to provide power for the RTC only when the ain power supply is switched off.
The resistors in the lower left corner of this sheet (R31, R33-34, R36, R39, R41, R43-44), are
i portant configuration resistors, these ensure that the CPU boots in the correct ode.

SPI Bus
The SPI bus connects the ARM CPU to the Sharc DSP and the PIC icrocontroller on the Control
board. The SPI bus is used at power up to load software into the Sharc DSP. For this, the ARM
CPU is the SPI aster and the Sharc DSP is the SPI slave. Once this is co pleted the SPI bus is
then used for co unication between the control board icrocontroller and the ARM CPU. For
this, the control board icro is the SPI aster and the ARM CPU beco es a slave.
Note that a control signal TXD2 is used to tell the control board icro when it is allowed to take
over the SPI bus. TDX2 is and output fro the ARM CPU. It is high while the DSP software is
being loaded, and goes low when this is finished to indicate that the control board can beco e the
SPI aster and start co unication.

I2S audio signals
I2S audio interfaces are provided between the ARM CPU and the DSP. Audio can be sent in both
directions, though in the NH00 only the outputs fro the ARM are used. The DSP is the I2S aster
and the ARM is a slave. All audio on this interface is trans itted at a sa ple rate of 176.4kHz.
Signal Name Function Source
ARM-BCLK I2S bit clock (11.2896MHz) DSP
ARM-MCLK I2S aster clock (not used because ARM does
not need aster clock)

ARM-SOUT0 I2S data out channel 0 (deck A) ARM
ARM-SOUT1 I2S data out channel 1 (deck B) ARM
ARM-SOUT2 I2S data out channel 2 (not used in NH00) ARM
USB
The ARM CPU provides 3 full speed (12Mbit/s) USB host ports. Each port uses a differential pair
of signals; USBP0/USBM0, USBP1/USBM1 and USBP2/USBM2 are the 3 ports.
I2C
An I2C port is provided; SDA (data) and SCL (clock). The ARM is the I2C aster.
This is used to configure the audio codec. It is also connected to the RTC chip although at present
the RTC chip is never co unicated with.

Serial ports
The ARM CPU provides 3 serial ports, of which we ake use of 2. TXD0/RXD0 are used for
debugging purposes, and this serial port is accessible on the NH00 I/O board. TXD1/RXD1 are not
used on the NH00 (on KA3 it is used for the iPod interface). RXD2/TXD2 are not used as a serial
port; TXD2 is a si ple control signal as entioned earlier.
Display interface
The ARM CPU drives the LCD odule using the following signals:
Signal name Function
SPCLK Pixel clock
VSYNC Vertical sync signal
HSYNC Horizontal sync signal
BLANK Blanking signal
BRIGHT Pulse width odulated (PWM) signal controls brightness of LCM backlight
P17 Used for fra e reverse signal
P12/P8/P4/P0 Used for D0..D3 4 bit video data
Status L Ds
D1 (red) and D2 (green) are status LEDs that can be used to see if the CPU has booted correctly.
Nor ally, the red LED will light briefly at power up then the green one will co e on instead.
If this fails to happen it indicates that the CPU has failed to boot for so e reason.
SH T 2 – I/O & PSU
This sheet shows the I/O connections, power supplies and power control.
Connections to I/O board
PL2-3 are 50 way high density connectors that connect the various signals to the I/O board:
I2S audio signals
I2C bus
SPI bus
LCD interface
Serial ports
Power control signals (OFF, POWER, POWERFAIL)
Codec reset signals (ADC_RESET, DAC_RESET)
USB ports
The 3 USB ports are provided on PL4-6. USB host ports are required to provide a 5V power supply.
IC9 is a protection device that is designed to protect the syste fro faults in the external USB
devices. It li its the current to a axi u of 0.9A per port, and detects short circuits. If a fault
occurs, !USBFAULT will go low. This is buffered by IC7 and reported back to the CPU. The
power for the USB ports can be turned off by the CPU using GPIO13.
IC8 is an analogue switch that switches the USB signals for one of the ports. In the KA3, PL6 is
connected to the iPod dock, and the analogue ux can disable the USB port when the iPod is used
in serial ode. In NH00, PL6 is a nor al USB port, so IC8 will always pass the USB signals.
PL9 is for the iPod serial port which is not used in NH00.

LCD backlight control
IC10 and associated co ponents provide an adjustable voltage to drive the LCM backlight. The
signal BRIGHT is a PWM signal fro the ARM CPU. R67/R69/C15 scales and filters this to a DC
level, which connects to the adjust pin of the voltage regulator IC10. IC10 will act so as to aintain
1.25V between its output and adjust pin, therefore the output will follow 1.25V above the adjust
pin. This drives the LCM backlight.
Core supply and power sequencing
IC11 is an adjustable voltage regulator providing the 1.8V core supply for the ARM CPU.
The ARM CPU needs the I/O supply to co e up so e ti e before the core supply. If this is not
done, the CPU so eti es fails to boot up due to a bug in the IC. To achieve this, a power
sequencing circuit is e ployed to turn off the input to IC11 for a short ti e at power up.
IC16 is a reset generator IC, the output of which will stay low for approxi ately 240 s after the
3.3V rail co es up. This signal is inverted by TR1 and then controls the gate of MOSFET TR2.
TR2 will therefore be off for 240 s after power up, so the 1.8V core supply will co e up 240 s
after the 3.3V rail.
SH T 3 – DSP
This sheet shows the SHARC DSP IC13, which is used for so e of the audio processing. Audio
fro the ARM is processed before being trans itted to the codec. Audio fro the codec is
processed before being trans itted to the ARM (the latter is not used in the NH00).
The DSP uses a 1.2V core provided by regulator IC18. The I/O supply is 3.3V. IC15 is a
22.5792MHz oscillator used by the DSP to generate all the clocks in needs internally using phase
locked loops.
The software for the DSP is loaded shortly after power up using the SPI bus, as described earlier.
Configuration resistors R84, R82 and R85 are i portant and ensure the DSP boot in the correct
ode with the correct internal clock frequency.
Audio interfaces
The DSP has audio interfaces to the ARM and the codec. In both cases the DSP is the I2S aster.
The interface with the ARM is descibed earlier.
The following signals ake up the interface with the codec, these run at 44.1kHz sa ple rate.
Signal Name Function Source
DSP-BCLK I2S bit clock (2.8224MHz) DSP
DSP-MCLK I2S aster clock (11.2896MHz) DSP
DSP-LRCLK I2S word clock (44.1kHz) DSP
DSP-SIN0 I2S data in channel 0 (not used in NH00) CODEC
DSP-SIN1 I2S data in channel 1 (not used in NH00) CODEC
DSP-SOUT0 I2S data out channel 0 (deck A) DSP
DSP-SOUT1 I2S data out channel 1 (deck B) DSP
DSP-SOUT2 I2S data out channel 2 (not used in NH00) DSP
Status L D
D5 is a red LED that shows the status of the DSP. Nor ally, this will turn on at power up, then turn
off while the software is loaded into the DSP, before turning on again once the software starts
running. If the behaviour is different then it indicates a proble with the DSP.

SHEET 1 – CODEC
This sheet shows the audio codec audio input and output circuitry muting and power supplies for
the analogue section.
The design features analogue inputs for a record function though the parts for this are not fitted
since the feature was removed from the product. 2 channels of audio are input on J3. Op-amp U3
and associated components form an input buffer having a gain of -0.4 and DC offset of +2V to
ensure the signal is at the correct levels for the codec. D3 and D8 provide limiting to ensure the
codec is not damaged in the event of large signal levels being applied. None of the components in
this section are fitted except C38 and C60; these have 0 ohm resistors fitted to ground the analogue
inputs of the codec.
U2 is a Cirrus Logic CS42406 audio codec. I2S audio is received from the CPU board for
conversion to analogue audio. I2S_TX0 and I2S_TX1 are the serial audio data for deck A and B
respectively. I2S_BCLK is the bit clock I2S_LRCLK is the word clock and I2S_MCLK is the
master clock.
The codec is configured by software via the I2C signals SDA (data) and SCL (clock).
!DAC_RESET is used to reset the DAC (active low) and !ADC_RESET resets the ADC (also
active low).
4 analogue outputs from the codec are used for Deck A (left + right) and Deck B (left + right)
outputs. These are AC coupled by C29 C50 C54 and C26 to remove the 2V DC offset that the
signal has at the codec output.
U1-A and associated components form a 2nd order low pass butterworth filter with corner frequency
of 50kHz approximately and a gain of -1.25. All 4 output channels use the same circuit.
Q1-4 are muting transistors. When switched on these clamp the audio outputs to ground to ensure
no pops or clicks are heard at the output when the system is powered up or down.
The muting is controlled by the MUTEC1 output of the codec. When MUTEC1 is high the outputs
will be muted. Transitors Q5-6 buffer the muting signal. R23 pulls the base resistors of Q1-4 down
to -4V to ensure the transistors are completely off when the system is not muted.
The MUTEC1 pin can be controlled by software to ensure that the system is muted when necessary.
MUTEC will always be high following power up and the software waits until the codec has been
initialised before taking it low. This mutes pops and thumps during power up and initialisation. The
software also controls muting at power down whether it is the user putting the unit into standby
mode or the power is unplugged. In the latter case the software receives a power fail signal to warn
it that the power is about to go away and it mutes the system before any unpleasant noises are
heard.
The audio op-amps use +/-4V supply rails. The codec +VA supply also uses the +4V rail. U9 is a
low drop out voltage regulator that derives the +4V rail from the system +5V rail. U7 is a charge
pump voltage inverter that generates a -4V supply from the +4V rail.

SHEET – POWER
This sheet shows the system power supply and the power control circuit.
The system is powered from a 12V DC power source; this is input on connector J8. D1 is a schottky
diode that ensures the system is not damaged should the user accidentally connect a power supply
with incorrect polarity. L1/C3/C20 are and EMC filter to reduce radiated and conducted emissions.
U5 and associated components form a switching regulator to provide the system +5V power supply.
This in turn is regulated by linear regulator U8 to derive the system +3.3V supply.
Power detect circuit: Comparator U10B and associated components provide a power detect circuit
to send the CPU and early warning that the external power supply has been unplugged or switched
off. Normally the output of the comparator will be low. If the input voltage falls below 10.8V then
the output will go high.
The software uses this POWERFAIL signal to mute the audio output and save system parameters to
flash so that the system can be restored after a power failure.
Power control circuit
U6 is a small PIC microcontroller than runs software to control the system power supply. U6 is
powered from a permanent +5V supply +5VPERM provided by U4.
The PIC controls the ON/OFF pin of 5V regulator U5. Since the 3.3V supply is derived from the
+5V supply both supplies are enabled together.
POWER_SW is the signal from the front panel power switch. It is high when the switch is pressed.
The power switch is monitored by both the PIC and main CPU. The signal is buffered by U10-D
prior to being sent to the CPU. This ensures that the signal POWER is never asserted high while the
system power supply is switched off (which could damage the CPU).
!OFF is a control signal from the CPU to request that the power is turned off. It is normally high
and goes low when the CPU wants the power to be turned off.
The power control works in the following way: When the 12V external power is first applied the
PIC will keep the system power supply switched off and will wait for the power switch to be
pressed. Only then will the the PIC will turn on the system power supply allowing the main CPU to
start up.
Once the system is running the main CPU will monitor the power switch. If the power switch is
pressed the main CPU will close down the system mute the audio output and save key parameters
to flash. Having done this the main CPU will set the !OFF signal low. This indicates to the PIC that
the CPU wishes to turn off the power supply and the PIC will respond by switching off the power.
The PIC also monitors the power switch while the system is running to detect if the power button is
pressed and held down for >7 seconds. If this happens the PIC will turn off the power. This
provides a way to turn off the power in the event that the main CPU software has crashed.

SHEET 3 – Connectors
This sheet shows the connection to other boards in the system and also the fader start inputs.
The CPU board plugs into 2 50 way headers J11-12.
The Control board connects to J16 via a 26 way ribbon cable.
The LCD display connects to J15 (data and power) and J14 (backlight).
It can be seen that the I/O board is used to route signals between the CPU board and the control
board and LCD module.
J6-7 are the fader start inputs designed to connect to mixers for automation. Each fader start
connector carries 2 control signals. There is no ground connection so the system relies on the audio
also being connected in order to provide a ground.
The 4 fader start signals are sent to the control board microcontroller.
D4-7 and R13-16 provide voltage limiting to protect the micro.
J1-2 are the USB connectors on the rear panel (USB2 and USB3). These are connected to the CPU
board via J9-10.
J13 is a debug connector. It can be connected to a PC to test and debug the system. A level
transceiver is required to convert the 3.3V levels to RS232 levels for the PC.
