MAX3963 155Mbps Preamplifier for FDDI and ATM LAN Fiber Optic Receivers General Description: The MAX3963 is a low-noise transimpedence preamplifier for FDDI and 155Mbps ATM optical receivers. The MAX3963’s dynamic range is optimized for use in multimode LED-based applications. The preamplifier converts a small photodiode current to a differential voltage, with typical transimpedance of 2K.Input-referred noise of only 21nA allows detection of signal as small as 267nA, while pulse-width distortion is only 85ps with a 60uA input signal. In a 1300nm multimode receiver, with responsivity of 0.7A/W, the MAX3963’s dynamic range spread from -36dB to -13.7dBm.The circuit operates from a single +5V supply, and typically consumed only 60mW power. The MAX3963 die includes a filter connection, which provides positive bias for the photodiode through a 1K resistor to VCC. The feature, combined with the small die size, allows the MAX3963 to fit easily into a TO-style package with a photodiode. The differential outputs are back terminated with 60 per side, allowing the easy use of filters to improve sensitivity. The MAX3963 is designed to be used with the MAX3964 limiting amplifier IC. It is available in an 8-pin SO package and as dice.
