3 Description

The DS560MB410 is a low-power, high-performance

four-channel linear equalizer supporting multi-rate,

multi-protocol interfaces up to 28 GBd using fourlevel

pulse amplitude modulation (PAM4), or up to

32 GBd using non-return-to-zero (NRZ) modulation.

It is used to extend the reach and robustness of highspeed

serial links for backplane, midplane, and active

copper cable (ACC) applications. The DS560MB410

can increase the reach between two ASICs by 18+ dB

beyond the normal ASIC-to-ASIC reach.

Each channel operates independently with a userselectable

CTLE boost profile optimized for equalizing

either PCB or copper cable loss profiles. The linear

nature of the DS560MB410’s equalization preserves

input signal characteristics traveling through the

redriver. This transparency allows link partner ASICs

to negotiate Tx equalizer coefficients freely during link

training and to support individual lane Forward Error

Correction (FEC) pass-through in mission mode with

minimal effect on latency.
