Introducing SYZYGY™

An open standard for high-performance peripheral connectivity.

  • Low cost, compact, high-performance connectors
  • Pin count economizes available FPGA I/O
  • Low cost cable options
  • FREE to license


High Performance Prototypes

Rapid prototyping with off-the-shelf single-purpose peripherals.

System Integration and Testing

Build complex systems from smaller building blocks to iterate quickly and reduce cost. Create custom test systems for production functional testing.

Evaluation Systems

SYZYGY is a perfect platform for your next high-performance semiconductor evaluation board.

Typical Peripherals

Data Acquisition
Machine Vision
Digital Communications
Software-Defined Radio
Video Output
Multi-Channel I/O

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.
Interface Pin Count MHz / Pin
SYZYGY STD103250500
SYZYGY XCVR101850200
SYZYGY XCVR (gigabit pins)485005,000
FMC LPC207250500
FMC LPC (gigabit pins)245005,000
FMC HPC7220050500
FMC HPC (gigabit pins)10405005,000
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.
