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 SE1031 is a fully integrated,
silicon bipolar transimpedance amplifier; providing
wideband, low noise preamplification of signal current
from a photodetector. It features differential outputs,
and incorporates an automatic gain control
mechanism to increase dynamic range, allowing input
signals up to 2.6 mA peak. A decoupling capacitor on
the supply is the only external circuitry required. A
system block diagram is shown after the functional
description, on page 3.
Noise performance is optimized for 2.5 Gb/s
operation, with a calculated rms noise based
sensitivity of –26 dBm for 10-10 bit error rate, achieved
using a detector with 0.5 pF capacitance and a
responsivity of 0.9 A/W, with an infinite extinction ratio
source.
