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
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.
