摘要： Circuitry for monitoring the operation of an optoelectronic transceiver includes a sequence of interconnected signal processing circuits for processing an analog input signal and producing a digital result signal, where the analog signal represents one or more operating conditions of the optoelectronic transceiver. The sequence of signal processing circuits include gain circuitry for amplifying or attenuating the analog input signal by a gain value to produce a scaled analog signal, an analog to digital converter for converting the scaled analog signal into a first digital signal, and digital adjustment circuitry for digitally adjusting the first digital signal to produce the digital result signal. The digital adjustment circuitry includes shifting circuitry configured to shift an input digital signal in accordance with a shift value so as to produce a digital shifted signal. The digital result signal is stored in memory in predefined locations accessible by a host.
