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 × 1015.
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.
