The HSDC extension module is intended for acquisition/generation and clock generation
purpose. When connected to an ADC demo-board it is intended as an acquisition system
for digital output bits delivered by ADC, either CMOS (HE14 P1 connector) or LVDS DDR
(SAMTEC QTH_060_02 P2 connector).
The board brief specification is shown below:
• 32 MB memory size for acquisition pattern;
• 2 16-bit channels CMOS up to 200 MHz;
• 16-bit LVDS DDR input data stream up to 320 MHz;
• On-board or external reference for signal generation.
In this section the specific requirement for the use with ADC1412D demo-board will be
shown.

2.1 HSDC extension module: hardware initialization
Before using the generation board, make sure that you connect the USB cable prior to
the supply.
When USB and power cable are connected, the HSDC-EXTMOD will light 3 red LEDs.
The green LED close to the PLL is only when it is locked (see section 3.3).
The red LED close to FPGA reports normal behavior when flashing ¼ on, ¾ off. Any
other flashing behavior reports a failure at initialization (see section 3.3).
2.2 HSDC extension module: CMOS connector description
The figure 5 shows a brief description of the hardware connection on the HE14
connector.
For proper use of the acquisition board, make sure that resistor R86 (0 Ω) is connected
while R84 is removed.
