MAX3747 Series

The MAX3747A/MAX3747B multirate limiting amplifiers function as data quantizers for OC-3 through OC-48 synchronous optical network (SONET), Fibre-Channel, and Gigabit Ethernet optical receivers. They are pin-for-pin compatible with the SY88993V from Micrel Semiconductor, Inc. The amplifiers accept a wide range of input voltages and provide constant-level, current-mode logic (CML) output voltages with controlled edge speeds. The MAX3747A/MAX3747B output voltages are 800mVP-P. The MAX3747B has enhanced LOS operation under overload conditions.The MAX3747A/MAX3747B limiting amplifiers feature a programmable loss-of-signal detect (LOS) and an optional disable function (DISABLE) that can be combined to implement squelch.The MAX3747A/MAX3747B are available in a 3mm, 10-pin µMAX® package ideal for small form-factor receivers.Applications10G LX4 Transceiver Modules1G/2G Fibre Channel SFF/SFP Optical Transceiver ModulesGigabit Ethernet SFF/SFP Optical Transceiver ModulesMultirate OC-3 to OC-48 FEC SFF/SFP Optical Transceiver Modules
