Product Description
SiGe Semiconductor offers a portfolio of optical
networking ICs for use in high-performance optical
transmitter and receiver functions, from 155 Mb/s up
to 12.5 Gb/s.
SiGe Semiconductor’s SE1230 is a fully integrated
AGC amplifier aimed primarily at SONET OC-48 and
SDH STM-16 systems. The device may also be used
in any datacom application with input data rates up to
2.5 Gb/s.
The device is designed with differential I/Os and
signal levels compatible with SiGe Semiconductor’s
SE1030 and SE1031 transimpedance amplifiers. A
system block diagram is shown after the functional
description, on page 4
.
Optimum performance is provided by differential
connections but with appropriate terminations, the
device can also be used in single-ended mode if
required by the application.
