De-Emphasis and Receive Equalization
Check for Samples: DS42BR400 FEATURES DESCRIPTION The DS42BR400 is a quad 250 Mbps – 4.25 Gbps
CML transceiver, or 8-channel buffer, for use in
backplane and cable applications. With operation
down to 250 Mbps, the DS42BR400 can be used in
applications requiring both low and high frequency
data rates. Each input stage has a fixed equalizer to
reduce ISI distortion from board traces. The
equalizers are grouped in fours and are enabled
through two control pins. These control pins provide
customers flexibility where ISI distortion may vary
from one direction to another. 1 2 250 Mbps – 4.25 Gbps Fully Differential Data
