Overview
January 1997 ML4622, ML4624 Fiber Optic Data Quantizer GENERAL DESCRIPTION The ML4622 and ML4624 data quantizers are low noise, wideband, bipolar monolithic ICs designed specifically for signal recovery applications in fiberoptic receiver systems.
They contain a wideband limiting amplifier which is capable of accepting an input signal as low as 2mVP-P with a 55dB dynamic range.
This high level of sensitivity is achieved by using a DC restoration feedback loop which nulls any offset voltage produced in the limiting amplifier.
The output stage is a high speed comparator circuit with both TTL and ECL outputs.
An enable pin is included for added control.
The Link Detect circuit provides a Link Monitor function with a user selectable reference voltage.
This circuit monitors the peaks of the input signal and provides a logic level output indicating when the input falls below an acceptable level.
This output can be used to disable the quantizer and/or drive an LED, providing a visible link ...
