10-Gbps quad channel retimer with adaptive EQ, CDR and DFE

The DS100DF410 is four channel retimers with integrated signal conditioning. Each channel can independently lock to 10.3125 Gbps data rate to support 10GbE. The device includes a fully adaptive Continuous-Time Linear Equalizer (CTLE), Clock and Data Recovery (CDR) and transmit De-Emphasis (DE) driver. The DS100DF410 also includes a self calibrating 5-tap Decision Feedback Equalizer (DFE) to enable data transmission over long, lossy and crosstalk-impaired highspeed serial links to achieve BER < 1 × 10–15.

The programmable settings can be applied easily 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. Flow-through pinout and single power supply make the DS100DF410 easy to use.
