The Mercury Computer Systems/Echotek FPDP-PMC is a single-width PCI Mezzanine Card that bridges high-speed FPDP interfaces to PCI bus architectures. This module implements the ANSI/VITA 17-1998 standard for Front Panel Data Port connectivity, delivering sustained data rates up to 160 MBytes/sec with PECL clocking or 80 MBytes/sec with TTL control. Built on the PLX PCI9080 chipset with dual Direct Memory Access Controllers, it handles real-time signal acquisition, image processing, and data streaming in embedded systems. The card supports four distinct operational modes—transmitter master, receiver master, and receiver configurations—with flexible framing control from unframed through dynamic repeating frames. Dual FIFO buffers (configurable 8K × 32 or 32K × 32) with crossbar switching provide unidirectional data flow management. Factory-selectable memory configurations and software-controlled TTL and PECL termination adapt the module to varied signal environments.
