Abstract
A squelch detector receives a first input signal, a second input signal VM, a first reference voltage and a second reference voltage. The first input signal and the second input signal are collaboratively defined as a differential input signal. The difference between the first reference voltage and the second reference voltage is defined as a squelch threshold. According to the squelch threshold, the squelch detector generates a detected signal to indicate whether the differential input signal is valid.
