3 Description

The DS250DF410 is a four-channel multi-rate retimer with integrated signal conditioning. 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 DS250DF410 independently locks to serial data rates in a continuous range from 20.2752 Gbps to 25.8 Gbps or to any supported sub-rate (÷2 and ÷4), including key data rates such as 10.3125 Gbps and 12.5 Gbps, which allows the DS250DF410 to support individual lane Forward Error Correction (FEC) pass-through.
