ML4622 Datasheet | Micro Linear

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 parator circuit with both TTL and ECL outputs. An enable pin is included for added control. The Link Detect circuit provides a...
