CXB1572Q
Post amplifier for Optical Fiber Communication Receiver
Description
The CXB1572Q achieves the 2R optical-fiber
communication receiver functions (Reshaping and
Regenerating) on a single chip. This IC is also
equipped with the signal interruption alarm output
function, which is used to discriminate the existence
of data input.
