Cabling; Table 10: Analog-To-Digital And Digital To Analog Input Connector Pinout - VersaLogic Blackbird VL-EPU4562 Hardware Reference Manual

The EPU-4562/4462 uses a Texas Instruments ADS8668 eight-channel 12-bit A/D converter.
The converter has a 500 kilo-samples-per-second (ksps) aggregate sampling rate, with a 1.115 μs
acquisition time, high-impedance The converter is per-channel programmable for the following
input ranges:
±0.64 V

±1.28 V

±2.56 V

±5.12 V

±10.24 V

Communications with the A/D converter are handled by the FPGA, which uses the SPX slave
selection signal for SPI device 5 to enable the A/D read strobe for the SPI interface. Refer to the
VL-EPU-4562/4462 Programmer's Reference Manual (available on the EPU-4562/4462 Product
Support Web Page) for information on configuring the SPX registers for A/D access.
Refer to the Texas Instruments ADS8668 A/D Converter Datasheet
information.
This table provides the pinout of the Analog-to-Digital and Digital to Analog Input connector.

Cabling

The VL-CBR-2004 paddleboard is bundled with an adapter cable for connecting the Blackbird to
the VL-CBR-2004 paddleboard. This is a 12-inch, Pico-Clasp 20-pin to 20-pin cable.
If your application requires a custom cable, the following information will be useful:
