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.
