Figure 1-1. Block Diagram

The SFP+ module contains the following components and provisions:

  • PolarFire MPF200T-FCSG325 FPGA
  • PolarFire FPGA auxiliary circuit for power-up
  • Clocking and programing circuit
  • Line drivers
  • Limiting amplifiers
  • Optical communication:
    • Receiver optical sub-assembly (ROSA) required for optical communication
    • Transmitter optical sub-assembly (TOSA) required for optical communication
  • Provision for one high-speed serial TX/RX going form PolarFire FPGA to line driver/amplifier
  • A few side-band signals to control other circuit
