ML4621 General Description
The ML4621 data quantizer is a low noise, wideband monolithic IC designed specifically for signal recovery applications in fiber-optic receiver systems. It contains a two stage wideband limiting amplifier which is capable of accepting an input signal as low as 2mV 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 minimum signal discriminator 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 status.
