Description

The RCV1551 receiver provides

optical signal conversion and

processing. It contains an InGaAs

PIN photodiode and high

sensitivity, wide dynamic range,

transimpedance amplifier,

capacitively coupled to limiting

amplifier stages with PECL

output drivers. Also provided is a

loss of signal alarm.

The planar PIN photodiode

operates throughout the 1200 nm

to 1600 nm wavelength band. A

CMOS wide dynamic range

transimpedance amplifier

optimized for 155 MBd operation

provides low noise front end gain

for the RCV1551.

A low pass filter maximizes the

signal to noise ratio while

minimizing intersymbol

interference. The interface

amplifier provides signal

conversion and buffering for the

PECL complementary data

outputs. A complementary PECL

alarm output is also provided.

The receiver operates from +5 V

and -5.2 V or +5 V and Ground

power supplies. A 50/125 micron

multimode fiber pigtail is

included, assuring compatibility

with multimode and single mode

fiber optic systems.
