CXB1577Q

E96Z24-PS

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.

Features

• Output disable function (TTL input)

• Signal detection function (TTL/ECL output)

• Supply voltage supports both 3.3V/5.0V

Applications

• SONET/SDH:

622.08Mbps

• Fibre Channel:

531.25Mbps
