Abstract
A transceiver (14) for recovering two different types of manchester coded, optical data signals from a photodiode is disclosed. The transceiver (14) includes a preamplifier (28) that receives and differentially amplifies the optical signal to reject power supply noise. The output of the preamplifier (28) is applied to an AC coupler (30) that extracts DC signal components using a switching circuit to produce a purely differential signal. A post amplifier/quantizer (34) receives the purely differential signal from the AC coupler (30) and generates a quantized signal therefrom. The quantized signal is applied to a data filter, clock recovery and control logic system 36 (36) that recovers a clock signal from the data signal that is synchronized by every data edge of the quantized signal.
