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 +3.3 V power supply
◾ Input noise current = 360 nA rms when used with a 0.5 pF detector
◾ Transimpedance gain = 2.3 kW into a 50 W load (differential)
◾ On-chip automatic gain control gives input current overload of 2.6 mA pk and max output voltage swing of 300 mV pk-pk
◾ Differential 50 W outputs
◾ Bandwidth (-3 dB) = 2.4 GHz
◾ Wide data rate range = 50 Mb/s to 2.5 Gb/s
◾ Constant photodiode reverse bias voltage = 1.5 V (anode to input, cathode to VCC)
◾ Minimal external components, supply decoupling only
◾ Operating junction temperature range = -40°C to +125°C
◾ Equivalent to Nortel Networks AB89-A2A

APPLICATIONs
◾ SONET/SDH-based transmission systems, test equipment and modules
◾ OC-48 fibre optic modules and line termination
◾ ATM optical receivers
◾ Gigabit Ethernet
◾ Fibre Channel
