MAXIM INTEGRATED PRODUCTS  MAX3747BEUB+T  限幅放大器, 155Mbps至3.2Gbps, 2.97 V, 3.63 V, µMAX, 10 引脚, -40 °C

The is a 155Mbps to 3.2Gbps, low power SFP limiting amplifier in 10 pin µMAX package. It is multirate limiting amplifier function as data quantizer for OC-3 through OC-48 synchronous optical network SONET, fibre channel and gigabit Ethernet optical receiver. It is pin-for-pin compatible with the SY88993V from Micrel Semiconductor, Inc. The amplifier accepts a wide range of input voltages and provides constant level, current mode logic CML output voltages with controlled edge speeds, output voltage is 800mVP-P and has enhanced LOS operation under overload conditions. This limiting amplifier features a programmable loss of signal detect LOS and an optional disable function DISABLE that can be combined to implement squelch. It is used in gigabit Ethernet SFP/SFF optical transceiver modules, 1G/2G fibre-channel SFP/SFF optical transceiver modules, multirate OC-3 to OC-48 FEC SFP/SFF optical transceiver modules, 10G LX4 transceiver modules.
