SNLS460A – MAY 2013 – REVISED OCTOBER 2015 DS110RT410 Low-Power Multi-Rate Quad Channel Retimer
1 Features 3 Description The DS110RT410 is a four-channel retimer with
integrated signal conditioning. The device includes a
fully adaptive continuous-time linear equalizer
(CTLE), clock and data recovery (CDR), and a
transmit de-emphasis (DE) driver to enable data
transmission over long, lossy and crosstalk-impaired
highspeed serial links to achieve BER < 1 × 10–15.
For channels with a high amount of crosstalk, the
DS110DF410 should be used because it has selfcalibrating 5-tap decision-feedback equalizer (DFE). Each channel can independently lock to data rates
from 8.5 to 11.3 Gbps, and associated sub-rates
(divide by 2, 4, and 8) to support a variety of
communication protocols. A 25-MHz crystal oscillator
clock is used to speed up the CDR lock process. This
clock is not used for training the PLL and does not
need to be synchronous with the serial data.
The programmable settings can be applied using the …
