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.

Features
◾ Single +5 V power supply
◾ Input noise current = 45 nA rms when used with a 0.5 pF detector
◾ Transimpedance gain = 5.6 kW into a 50 W 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 W single-ended or 100 W 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

Applications
◾ SONET/SDH-based transmission systems, test equipment and modules
◾ OC-12 fibre optic modules and line termination
◾ ATM optical receivers
