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