概要

The DS280DF810 is an eight-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 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.

Integrated physical AC coupling capacitors (TX and RX) eliminate the need for external capacitors on the PCB. The DS280DF810 has a single power supply and minimal need for external components. These features reduce PCB routing complexity and BOM cost.

The advanced equalization features of the DS280DF810 include a low-jitter 3-tap transmit finite impulse response (FIR) filter, an adaptive continuous-time linear equalizer (CTLE), and an adaptive decision feedback equalizer (DFE). This enables reach extension for lossy interconnect and backplanes with multiple connectors and crosstalk. The integrated CDR function is ideal for front-port optical module applications to reset the jitter budget and retime the high-speed serial data. The DS280DF810 implements 2x2 cross-point on each channel pair, providing the host with both lane crossing and fanout options.

The DS280DF810 can be configured either via the SMBus or through an external EEPROM. Up to 16 devices can share a single EEPROM. A non-disruptive on-chip eye monitor and a PRBS generator/checker allow for in-system diagnostics.
