SYZYGY fills the gap between low speed, low pin-count Digilent PMOD devices and high-performance, high pin-count VITA 57.1 FMC peripherals. This chart shows SYZYGY, PMOD, and FMC standards as well as several model peripherals and where they fall on throughput-per-pin and pin count metrics.

Interface Pin Count MHz / Pin Min Max Min Max PMOD 4 8 1 50 SYZYGY STD 10 32 50 500 SYZYGY XCVR 10 18 50 200 SYZYGY XCVR (gigabit pins) 4 8 500 5,000 FMC LPC 20 72 50 500 FMC LPC (gigabit pins) 2 4 500 5,000 FMC HPC 72 200 50 500 FMC HPC (gigabit pins) 10 40 500 5,000

Note: Yes, all of these standards can go down to DC and some can go higher than we have here. This data basically illustrates what we consider to be the "sweet spot" for the interface. Your mileage may vary.
