DS250DF410ABMR Product Details

The DS250DF410ABMR 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 seriallinks while achieving a bit error rate (BER) of 10-15 or less.

Each channel of the DS250DF410ABMR independently locks to serial data rates in a continuousrange from 20.2752 Gbps to 25.8 Gbps or to any supported sub-rate (÷2 and ÷4), including key datarates such as 10.3125 Gbps and 12.5 Gbps, which allows the DS250DF410ABMR to support individual laneForward Error Correction (FEC) pass-through.

The DS250DF410ABMR has a single power supply and minimal need for external components. Thesefeatures reduce PCB routing complexity and BOM cost.

The advanced equalization features of the DS250DF410ABMR include a low-jitter 3-tap transmitfinite impulse response (FIR) filter, an adaptive continuous-time linear equalizer (CTLE), and anadaptive decision feedback equalizer (DFE). This enables reach extension for lossy interconnect andbackplanes with multiple connectors and crosstalk. The integrated CDR function is ideal forfront-port optical module applications to reset the jitter budget and retime the high-speed serialdata. The DS250DF410ABMR implements 2x2 cross-point on each channel pair, providing the host with lanecrossing, fanout, and multiplexing options.

The DS250DF410ABMR 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 non-disruptive on-chipeye monitor and a PRBS generator/checker allow for in-system diagnostics.


  • Quad-channel multi-rate retimer with integrated signal conditioning
  • All channels lock independently from 20.2752 to 25.8 Gbps (including sub-rates such as 10.3125 Gbps, 12.5 Gbps, and more)
  • Ultra-low latency: <500 ps typical for 25.78125-Gbps data rate
  • Single power supply, no low-jitter reference clock required, and minimal supply decoupling to reduce board routing complexity and BOM cost
