DS250DF210 Multi-Rate 2-Channel Retimer

Texas Instruments DS250DF210 Multi-Rate 2-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 DS250DF210 independently locks to serial data rates in a continuous range from 20.6Gbps to 25.8Gbps or to any supported sub-rate (÷2 and ÷4), including key data rates such as 10.3125Gbps and 12.5Gbps. This allows the DS250DF210 to support individual lane Forward Error Correction (FEC) pass-through. The DS250DF210 has a single power supply and minimal need for external components. These features reduce PCB-routing complexity and BOM cost. The DS250DF210 can be configured either through the SMBus or through an external EEPROM. Up to 16 devices can share a single EEPROM using Common Channel format. A nondisruptive, on-chip eye monitor and a PRBS generator or checker allow for in-system diagnostics.
