OC-12/STM-4 Receiver with

Clock Recovery

SRC12 Series

The SRC12 is a Receiver Module with internal clock recovery designed to

meet or exceed the SONET/SDH optical interface requirements at OC-12/

STM-4 (622 Mb/s) data rate. Highly reliable InGaAs/InP PIN photodiodes

are used to cover the entire long wavelength range from 1100 nm to 1550

nm.

The receiver features a low noise GaAs transimpedance IC with AGC ca-

pability to provide an extremely wide dynamic range and high sensitivity.

A Phase Lock Loop (PLL) circuit is included to perform the clock recovery

function and resampling of the data.

The SRC12 receiver requires a single +5 V supply. The DATA & CLOCKinter-

face signals are differential PECL while the SIGNAL DETECT outputs have

TTL interface.

The SRC12 module can operate over an operating temperature range of

0°C to +70°C (“H” option) or -40°C to +85°C (“I” option). It is housed in a

20-pin dual-in-line metal package with integral ST, FC or SC connector

receptacle or fiber pigtail (50 µm multimode fiber). The fiber pigtail is ter-

minated with ST, FC or SC connector.
