FPGA Mezzanine Card Interface
[Figure 2, callout 31]
The VCU128 evaluaon board supports the VITA 57.4 FPGA mezzanine card plus (FMC+ or
FMCP) specicaon by providing a subset implementaon of the high pin count connector at J18
(HSPC, high serial pin connector). The VITA 57.4 standard extends the VITA 57.1 FMC standard
by specifying two new connectors that increase the number of mul-gigabit interfaces from 10
to 24. Also, there is an oponal extension connector (the high serial pin connector extension, or
HSPCe) to boost pin-count by 80 posions, arranged in a 4x20 array. The VCU128 board does
not implement the high serial pin connector/HSPCe extension.
FMC+ connectors use a 14 x 40 form factor, populated with 560 pins. The connector is keyed so
that a mezzanine card, when installed on the VCU128 evaluaon board, faces away from the
board.
J18 FMC+/FMCP Connectors
This secon describes the J18 FMC+/FMCP connectors.
• Samtec SEAF series, 1.27 mm (0.050 in) pitch. Mates with SEAM series connector. More
informaon about SEAF series connectors is available on the Samtec website.
• The 560-pin FMC+ connector dened by the FMC specicaon (see Appendix A: VITA 57.4
FMCP Connector Pinouts) provides connecvity for up to:
○ 160 single-ended or 80 dierenal user-dened signals
