2.2.3 Audio circuit
2.2.3.1 RX Audio
KCH-20R has two RX Audio input channels, AFIA+/- and AFIB+/-. And the MPU selects the one of the two channels, and then applied
to digital potentiometer IC (IC22/XC3-010). (The channel to use is notified by serial communication from RF Deck.)
The digital potentiometer IC adjusts RX Audio signal amplitude equal to the value of selected volume step, and output it.
RX signal through digital potentiometer IC is put into codec IC (IC17/XC3-010). KCH-20R has several output method of RX audio
signal (Speaker port, Bluetooth headset, and micro SD card recording). When use speaker output path, this audio signals pass through
to output port of codec IC. When use other output method, codec IC convert this signal to digital data, and transmits to the MPU (IC14/
XC3-010).
That analog output signal from codec IC is converted to balanced signal by operational amplifier (IC18/XC3-010).
And converted signal goes to Class-D audio amplifier (IC2/XC3-011). The audio amplifier is controlled to shut-down or power-up, by
MPU.
2.2.3.2 TX Audio
KCH-20R has four microphone input channels. First one is connected to modular interface (J2/XC3-010), second is connected to
external interface connector (CN2/XC3-011). Third is Bluetooth headset. Fourth is micro SD recording playback. When use modular
interface or external interface, these two microphone signals are selected by analog multiplexer IC (IC29/XC3-010), and applied to
microphone amplifier. The microphone amplifier consists of operational amplifier and AGC. And its output is connected to Codec IC.
The total gain of amplifiers in Codec IC is set to 0dB. The output signal of codec IC is converted to balanced signal by operational
amplifier (IC28/XC3-010). The converted signals are switched by analog switch IC (IC35/XC3-010, IC36/XC3-010), and output to ei-
ther MICA+/- or MICB+/-. The output channel is notified from RF Deck by serial communication.

2.2.4.2 Memory Circuit
Memory circuit consists of the MPU and the Mobile DDR (IC23/XC3-010), the flash memory (IC29/XC3-010). The flash memory has
capacity of 256Mbit that contains the program for the MPU and stores the data. That program can be easily updated from external
devices. The Mobile DDR has capacity of 512Mbit. The MPU copies the program from the flash memory to the Mobile DDR. The MPU
uses the Mobile DDR as a work area.
2.2.4.3 Serial interface between RF deck and KCH-20R
KCH-20R is controlled by serial interface from RF deck. That interface consists of CAN transceiver (IC1/XC3-010), but that does not
support CAN protocol. UART communication is used between CAN transceiver and MPU.
2.2.4.4 LCD control interface
The MPU controls LCD through the LCD interface connector (CN57/XC3-010). LCD is controlled by parallel bus with 16bit data width.
2.2.4.5 Key detection
KCH-20R has 19 keys. The keys except the AUX key and Power key is included in key-matrix circuit. Key-matrix consists of 4 input
ports and 5 output ports. When key is pressed, the MPU starts scanning the keys and detects which key was pressed.
AUX key is connected to MPU independently. The power key is connected to RF deck through the RF deck interface connector (CN5/
XC3-011).
2.2.4.6 External I/O
KCH-20R has external interface connector (CN2/XC3-011). That interface has two output and two input terminals.
The output terminal is open collector type. The input terminal has level shift circuit, it permits input the 5V signal.
2.2.4.7 micro SD circuit
The micro SD card interface consists of 4bit data bus and control signals. Maximum data transfer speed is 36MHz.
2.2.5 Bluetooth Circuit
The main component of the Bluetooth circuit is Bluetooth IC (IC12/XC3-010) and level converter circuit.
The clocks of Bluetooth IC requires 19.2MHz for core and 32.768kHz slow clock (X1/XC3-010 and X2/XC3-010) for UART.
Bluetooth IC communicates to the MPU (IC14/XC3-010) on the HCI UART. Interface of UART & Digital audio (I2S) between the MPU
and the Bluetooth IC, have level conversion at the level converter IC (IC13/XC3-010 and IC11/XC3-010).
The Bluetooth IC is powered by 1.8V and 3.3V which are supplied from 2 discrete external regulators (IC5/XC3-010 and IC6/XC3-
010).
TX/RX frequency is 2400-2483.5MHz (79ch Hopping, 2402-2480MHz, 1MHz step). Transmitting power is +2dBm at Bluetooth an-
tenna input.
Bluetooth antenna is surface mount chip antenna (ANT1/XC3-010), and that is connected to the Bluetooth IC through the LC filter
(L30/XC3-010).
Fig.3 Bluetooth Circuit
Frequency configuration for Bluetooth is following:
There are two LO modes: 2X and Offset LO (OSLO). 2X where LO is 2*RF_FREQ (e.g. when transmitting at 2441MHz it is at
4882MHz). OSLO where LO is at (2/3)*RF_FREQ (e.g. when transmitting at 2441MHz it is at 1627.333MHz).
In RX the 2X is always used.
In GFSK TX if power is 10dBm or more then OSLO is used.
In EDR2 TX if power is -12dBm or more then OSLO is used.
In EDR3 TX if power is -12dBm or more then OSLO is used.
Otherwise 2X is used for TX as well.
