DS125DF1610FBE/NOPB

接口-信号缓冲器、中继器 16 Channel Retimer

The DS125DF1610 is a sixteen-channel multi-rate retimer with integrated signal conditioning features. The device includes a fully 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 DS125DF1610 independently locks to serial data at 9.8 to 12.5 Gbps and the divide by 2, 4 and 8 sub-multiples. A simple external oscillator ±100ppm that is synchronous or asynchronous with the incoming data stream is used as a reference clock. Integrated 4x4 cross point switches allow for full non-blocking routing or broadcasting within each quad of the DS125DF1610.

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.
