SMI4039 40-45 Gbps 2:16 DQPSK CDR/Demultiplexer
Product Description
4Adjustable input threshold and sample clock phase
for each input channel
SMI4039 accepts single-ended or differential 40 to 45
Gbps NRZ serial data streams and demultiplexes the
data into sixteen parallel output channels consistent
with the SFI-5 standard.
4Reference clock input port at 1/4th of the SFI-5.1
baud rate
