CXB1577Q
Post-Amplifier for Optical Fiber Communication Receiver
Description
The CXB1577Q achieves the 2R optical-fiber
communication receiver functions (Reshaping and
Regenerating) on a single chip. This IC is equipped
with the signal detection function, which is used to
enable TTL/ECL outputs. Also, the output disable
function performs the output shutdown. 3.3V/5.0V
can be used for the supply voltage.
40 pin QFP (Plastic)
