EQ50F100
1Gbps - 6.25 Gbps Backplane Equalizer
General Description
The EQ50F100 is a equalizer designed to compensate
transmission medium losses and reduce the medium-
induced deterministic jitter. It is optimized for operation from
1Gbps to 6.25Gbps, on printed circuit backplane for up to
30" of FR4 striplines with backplane connectors at both
ends. It is code independent, and functioning equally well for
short run length, balanced codes such as 8b/10b, commonly
used in multiplexed 1.25 Gbps Ethernet Systems.
The equalizer uses differential CML inputs and outputs with
feed-through pin-outs, mounted in a 3 mm x 3 mm 6–pin
leadless LLP package. It is powered from single 1.8V supply
and consumes 85 mW.
