5.4 USB 2.0 OTG
JC5 USB 2.0 OTG interface is connected directly to the USB OTG pins of the expansion
connector JC3 and is ONLY OPERATIONAL WHEN USING IGEP™COM MODULE as processor
board. Check IGEP™COM MODULE to see the possibilities of this interface.
JC5 USB 2.0 OTG interface can be used as the default power input by using a USB-A to mini-AB
socket cable. It is possible to boot the IGEP™COM MODULE and operate the whole radar using
this port, in a standalone operation mode.
When using JC5 USB 2.0 OTG interface to power IGEP™RADAR SENSOR ORION
you must ensure your power source can supply up to 500mA, plus the current
consumption of the processor board connected.
IGEP™RADAR SENSOR ORION can be powered through any of several
connectors, JP1, JC1, JC2 or JC5. You MUST USE ONLY ONE of these connectors to power the
board. If you power the board using 2 or more of these connectors at the same time the board
will be DAMAGED.
In HOST mode, you MUST power the board using the JP1 connector. The USB OTG port can
only source 100mA. This is enough to drive a single low-power device but if you connect a USB
hub you’ll probably also need external power for the USB hub.

5.6 DDS MODULATOR INTERFACE
IGEP™RADAR SENSOR ORION includes a complete Direct Digital Synthesizer acting as the
frequency modulator of the radar system.
This section describes the main modulation parameters and the programming registers of DDS
Modulator that can be programmed through SPI Link on JC2 or JC3 connectors. The next figure
is a typical example of a basic triangular sweep modulation:
Figure 6: TRIANGULAR DDS MODULATION PARAMETERS
5.6.1 DDS MODULATOR BASIC PARAMETERS AND EQUATIONS
FBASE , BASE FREQUENCY: This is the reference oscillator Frequency in MHz, that in this
RADAR has been fixed to F0[MHz]=50.
FSTART, START FREQUENCY: This is the DDS parameter that fixes the RF output frequency
in which the PLL will force to start the modulation sweep.
RF OUTPUT FREQUENCY START (F1[MHz]) is obtained from FSTART by the following equation:
F1[MHz]=2048*FSTART[dec]*F0[MHz]/2^24 (I)
example: F1=24GHz=24000MHz → FSTART=3C0000 [hexa] = 3932160 [dec]
NOTE: Careful has to be taken to work in hexadecimal and/or decimal format. The use of
hexadecimal format is needed because programming the DDS use this format.

14
ΔF: STEP, (FREQUENCY STEP): Is the DDS parameter that fixes the RF output frequency
variation that we want from one basic interval to the next one.
RF OUTPUT FREQUENCY VARIATION (ΔF[Hz]) is obtained from STEP by the next equation:
ΔF[Hz]=106*STEP[decimal]*F0[MHz]/2^24 (II)
example: STEP=28 [hexa] →ΔF[kHz]=243,712kHz.
Maximum allowed value of STEP: 400000 [hexa].
NINCR, NUMBER OF INCREMENTS: Is the number of the RF output frequency increments
we want to have within a modulation sweep. The maximum allowed NINCR is FFF [hexa] →
4095[decimal].
There are two ways to complete a modulation sweep:
-By controlling the frequency steps through activation of the CTRL port.
-By programming an automatic frequency increment through the next parameter:
SLOPE: BASIC INTERVAL DURATION: Is the DDS parameter that fix the duration we want for
each basic interval of the modulation sweep (TBASE).
TBASE is obtained (in nanoseconds) from SLOPE parameter by the next equation:
TBASE[ns]=1000*SLOPE[decimal]/F0[MHz] (III)
example: if we want a modulation sweep duration of 10ms with the above value of NINCR (FFF
[hexa]), we should program SLOPE at value '7A' (hexa) →122[decimal] → TBASE=2,44us →
NINCR[decimal]*TBASE = 10ms.
Maximum allowed value for SLOPE is: 7FF [hexa].
5.6.2 DDS PROGRAMMATION THROUGH SPI LINK
The next figures show the SPI serial interface timing and the basic clock timing:

THIRD WORD: DTUV (Example: D3C1)
STEP[hexa]=QRS (Example: 567)
FOURTH WORD: 2QRS (Example: 2567)
FIFTH WORD: 3000
NINC[hexa]=NOP (Example: 89A)
SIXTH WORD: 1NOP (Example: 189A)
SLOPE[hexa]=KLM (Example: 7CD)
SEVENTH WORD: 6KLM (Example: 67CD)
SPI programming must follow this 7 word format, each word made of 4 hexadecimal values:
GHIJ CXYZ DTUV 2QRS 3000 1NOP 6KLM
in the example:
0B8F C234 D3C1 2567 3000 189A 67CD
At each falling edge of FSYNC, it is sent by SDATA line a 16bit frame (4 value hexadecimal
word), starting by the most significant bit. Each data bit is sampled at each SCLK falling edge.

5.8 CONTROL PORTS
There three input ports (active high) used to control the radar board: switch among different IF
amplifiers and filters or start DDS modulation.
CTRL: This is a Radar Board INPUT. The activation of this pin will give the possibility to start
DDS modulation sweep (with the previously programmed scheme through SPI interface)
when ADC CS is activated by the first time (first sample read). This will let a perfect
synchronization between modulation start and IF signal sampling.
CTL1: This is a Radar Board INPUT that switches the IF signal to a Narrow Band Pass Filter.
CTL2: This is a Radar Board INPUT. This pin switches to a Doppler Filter on the IF section.
When EXPANSION-II (JC2 CONNECTOR) is used, the CONTROL ports are:

5.9 TEST PORTS
There are 4 RF Coaxial connectors that can be used to monitor different radar internal signals
for test or educative purposes: JF1, JL1, JD1 and JD2 ARE HIROSE P/N: UFL-R-SMT (01)
JF1: UFL connector to monitor Radar IF Signal
JL1: UFL connector to monitor Transmitter VCO Control Signal
JD1: UFL connector to monitor DDS Modulator Output Signal
JD2: UFL connector to monitor DDS Modulator Synchronism Signal
SYNC: This is a Radar Board OUTPUT. The DDS can be programmed through SPI to make that
this pin is activated at the end of the modulation sweep or to indicate each frequency slope
made by the DDS during the modulation sweep.
IGEP™RADAR SENSOR ORION TEST PORTS are outputs with maximum +5Vdc
voltage level. PERMANENT DAMAGE WILL OCCUR if any voltage is applied to
these ports.
5.10 EEPROM
The on-board EEPROM, implemented with the AT24C01B serial EEPROM, provides 1KB of user
data storage. The serial EEPROM is connected through I2C interface and is address [0,0,1 ].
