The DS110DF1610 is a sixteen-channel multi-rate retimer with integrated signalconditioning. The device includes a full adaptive Continuous Time Linear Equalizer (CTLE), DecisionFeedback Equalizer (DFE), clock and data recovery (CDR), and a transmit FIR filter to enhance thereach and robustness over long, lossy, crosstalk impaired high speed serial links to achieve BER< 1×10-15.
Each channel of the DS110DF1610 independently locks to serial data at 8.5 to 11.3 Gbpsand any supported sub-multiple. A simple external oscillator (±100ppm) that is synchronous orasynchronous with the incoming data stream can be used as a reference clock to speed up the lockprocess. Integrated 4x4 cross point switches allow for full non-blocking routing or broadcastingwithin each quad of the DS110DF1610.
Programmable transmit FIR filter offers control of the pre-cursor, main tap andpost-cursor for transmit equalization. The fully adaptive receive equalization (CTLE and DFE)enables longer distance transmission in lossy copper interconnects and backplanes with multipleconnectors.
A non-disruptive mission mode eye-monitor feature allows link monitoring internal to thereceiver. The built-in PRBS generator and checker compliment the internal diagnostic features tocomplete standalone BERT measurements. Built-in JTAG enables manufacturing tests.
