2 Description

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 < 1×10-15.

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 connectors.

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.
