FPDP / FPDP II Digital Parallel I/O PMC Module - DPIO2

The FPDP II Digital Parallel I/O DPIO2 is the second generation high speed digital parallel input output PMC module from VMETRO. The new DPIO2 architecture handles the transfer speed requirements imposed by the 64 bit 66 MHz PCI interface and the FPDP II 400 MByte/s improved bandwidth. The advanced capabilities of the linked-list DMA controller combined with the I/O handling features of the front-end FPGA will handle most data frame formats used in the data acquisition and signal processing environments. The speed is achieved by using a clock rate of 50 MHz clocking data on both edges. The module also supports the original FPDP and the basic card comes with the standard FPDP TTL signaling. A mezzanine card can be added as a Personality Module for other signal standards such as LVDS, PECL and RS-422.

In large volume deliveries, the generous capabilities of the on-board FPGAs have potential for custom programming for special handling of data formats such as timestamp insertion and specific framing.
