It is used to extend the reach and robustness of long, lossy, crosstalk-impaired high-speed serial links while achieving a bit error rate (BER) of 10-15 or less. Each channel of the DS280DF810 independently locks to serial data rates in a continuous range from 20.2 Gbps to 28.4 Gbps or to any supported sub-rate (÷2 and ÷4), including key data rates such as 10.1376 Gbps, 10.3125 Gbps, and 12.5 Gbps, which allows the DS280DF810 to support individual lane Forward Error Correction (FEC) pass-through.
