2 ds250df410 snls527 ? february 2016 www.ti.com product folder links: ds250df410 submit documentation feedback copyright ? 2016, texas instruments incorporated 4 description (continued) the ds250df410 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 ds250df410 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 ds250df410 implements 2x2 cross-point on each channel pair, providing the host with lane crossing, fanout, and multiplexing options. the ds250df410 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-chip eye monitor and a prbs generator/checker allow for in-system diagnostics.
