Final
Applications
§ SONET/SDH-based transmission systems, test
equipment and modules
§ OC-12 fibre optic modules and line termination
§ ATM optical receivers
Features
§ Single +5 V power supply
§ Input noise current = 45 nA rms when used with a
0.5 pF detector
§ Transimpedance gain = 5.6 kΩ into a 50 Ω load
(single -ended)
§ On-chip automatic gain control gives input
current overload of 2.6 mA pk and max output
voltage swing of 300 mV pk-pk
§ 50 Ω single-ended or 100 Ω differential wire bond
selectable outputs
§ Bandwidth (-3 dB) = 400 MHz (min)
§ Wide data rate range = 10 Mb/s to 622 Mb/s
§ High input bias level = 2 V
§ Minimal external components, supply decoupling
only
§ Operating junction temperature range = -40°C to
+95°C
§ Equivalent to Nortel Networks AB53
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 SE1010W 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 automatic gain control
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 622 Mb/s
operation, with a calculated rms noise based
sensitivity of –35 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.
