Gennum's GN1032W is a fully integrated, silicon germanium 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.

• Single +3.3 V power supply
• Power dissipation = 145 mW (typ)
• Input noise current = 250 nA rms
• Transimpedance gain = 3.6 kΩ into a 100Ω load (differential)
• 100Ω (differential) outputs
• Bandwidth (-3 dB) = 2.05 GHz
• Wide data rate range = 155 Mb/s to 2.5 Gb/s
• Operating junction temperature range = -40°C to +125°C

• SONET/SDH-based transmission systems, test equipment and modules
• OC-48 fibre optic modules and line termination
• ATM over SONET/SDH
• Gigabit Ethernet
• 2x Fibre Channel
