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.

        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.
