155Mbps to 3.2Gbps, Low-Power SFP Limiting Amplifiers
155Mbps to 3.2Gbps, Low-Power SFP Limiting Amplifiers Function as Data Quantizers for OC-3 through OC-48 Synchronous Optical Network (SONET), Fibre-Channel, and Gigabit Ethernet Optical Receivers
The MAX3747/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 MAX3747 output voltage level is 500mVP-P and the
MAX3747A/MAX3747B output voltages are 800mVP-P.
The MAX3747B has enhanced LOS operation under overload
conditions.
The MAX3747/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 MAX3747/MAX3747A/MAX3747B are available in a
3mm, 10-pin µMAX® package ideal for small form-factor
receivers.
