Interface Comparison

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.

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.
