ML4624 Fiber Optic Data Quantizer
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 enablepin 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 status.
