5 Gb/s Transimpedance Amplifier Final 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 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 SE1030W is a fully integrated, silicon bipolar 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.
A system block diagram is shown after the functional description, on page 3.
Noise performance is optimized for 2.
5 Gb/s operation, with a calculated rms noise based -10 sensitivity of –26 dBm for 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.
