SCD-20

RS-422

8 - 16 bit
Parallel

General
purpose
parallel and
synchronous
serial data
transfer

The different SCD boards differ primarily in signal level. Configurable through Field Programmable Gate Array (FPGA) files. Standard FPGAs shipped with SCD products include:
·  External clock with TXT looped from RXT
·  Internal clock from the SCD
·  SSD (synchronous serial) option with 1, 2 or 4 input channels, 1 input and 1 output, or synchronous serial output
·  SCD-8, 2-channel (input/output) 8-bit parallel
Custom FPGAs are also available.
