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 2, 4 and 8) to support a variety of communication protocols. A 25 MHz crystal oscillator clock is used to speed up the CDR lock process. This clock is not used for training the PLL and does not need to be synchronous with the serial data.

The programmable settings can be applied using the SMBus (I2C) interface, or they can be loaded via an external EEPROM. An on-chip eye monitor and a PRBS generator allow real-time measurement of high-speed serial data for system bring-up or field tuning.
