IEEE 802.3bj was developed in response to the rapid growth of server, network and internet traffic. The standard meets the need for higher data rates over backplanes and copper cables for 100 Gbit/s throughput.


  • - Compliant with IEEE802.3bj, Clause 91
  • - Support for KR4 (528,514), KP4 (544,514) Reed-Solomon (RS) Codes
  • - Corrects up to seven (KR4) or up to 15 (KP4) errorenous symbols

Device Utilization and Performance

100 Gbit/s coded throughput at 625 MHz. Decoding latency of 92.8 ns at 625 MHz. Latency of 1.6 ns at 625 MHz in bypass mode. Bit Error Rate 10-11 at 8.8 dB at 8.8 dB (EB/N0) Block Error Rate 10-8 at 8.7 dB at 8.7 dB (EB/N0)
