General Description

The DS125DF410 is four channel retimer with integrated signal conditioning.

The device includes a fully adaptive Continuous-Time Linear Equalizer (CTLE), self calibrating 5-tap Decision Feedback Equalizer (DFE), Clock and Data Recovery (CDR), and transmit De-Emphasis (DE) driver to enable data transmission over long, lossy and crosstalk-impaired highspeed serial links to achieve BER < 1×10-15.

Each channel can independently lock to data rate from 9.8 to 12.5 Gbps, and associated sub rates (div by
