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 SE1000W is a fully integrated,
silicon bipolar transimpedance amplifier; providing
wideband, low noise preamplification of signal current
from a photodetector. It features single-ended or
differential outputs, selectable by wire bond options,
and
incorporates
an
mechanism to increase dynamic range, allowing input
signals up to 2.6 mA peak. For differential outputs, a
decoupling capacitor on the supply is the only
external circuitry required.
Noise performance is optimized for 155 Mb/s
operation, with a calculated rms noise based
sensitivity of –41 dBm for 10
-10
bit error rate, achieved
using a detector with 0.5 pF capacitance and a
responsivity of 0.95 A/W, with an infinite extinction
ratio source.
