SRC12-0403 Datasheet, PDF (1/4 Pages) OPLINK Communications Inc. – OC-12/STM-4 Receiver with Clock Recovery

OC-12/STM-4 Receiver with
Clock Recovery
SRC12 Series
Product Description
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.
