Equalization

Linear ReDriver increases Receiver Link Margin

with Sink-side DFE (Decision Feedback Equalizers)

Note

(1) e HBR3 receiver equalizer includes a CTLE cascaded with a one-tap adaptive DFE with

a feedback coecient limited to < 50mV. e DFE behavior is described below.

k = xk - d1* sgn (yk-1)

where:

k is the DFE di erential output voltage

k is the decision function output voltage

k is the di erential input voltage a er CTLE

1 is the feedback coecient

k is the UI sample

Decision Function
