CoaXpress Camera Side IP core

This is a CoaXpress V1.1 compliant IP core.
This standard uses coaxial cable up to 6.25Gbps (actual rate 5Gbps) per lane.
Data rate can be increased up to 25Gbps with a 4 lane setup.
Cable length can be scaled from 40m ~ over 100m. Installation is not limited by distance.
This IP core implements parts in need of performance as hardware and parts that require flexibility as software on CPU in FPGA, satisfying both needs effectively.
  • Supports sending stream packet, sending/receiving control packet, receiving trigger packet.
  • Auto idle insertion realizes image sending without frame buffer.
  • Using high speed transceiver in FPGA reduces PCB size
  • Minimum resources (4000LCs at 1lane)
  • Link speed can be changed from 1.25Gbps to 6.25Gbps
  • Supports 1, 2, 4 lanes.
