Texas Instruments DS280DF810 28Gbps 8-Channel Retimer
Texas Instruments DS280DF810 28Gbps 8-Channel Retimer 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 28.4Gbps or to any supported sub-rate (÷2 and ÷4). This includes key data rates such as 10.1376Gbps, 10.3125Gbps, and 12.5Gbps, which allows the DS280DF810 to support individual lane Forward Error Correction (FEC) pass-through. Integrated physical AC coupling capacitors (TX and RX) eliminate the need for external capacitors on the PCB. The Texas Instruments DS280DF810 has a single power supply and minimal need for external components. These features reduce PCB routing complexity and BOM cost.
