Abstract

A receiver includes a control module, a data receiving circuit and a masking circuit. The control circuit generates an enable signal according to a pair of differential signals provided by a transmitter. Triggered by the enable signal, the data receiving circuits generates an output signal according to the differential signals, and the masking circuit starts masking the output signal. After generating the enable signal, the control module starts providing a bias voltage to the differential signals such that the output signal has a first state. The transmitter adjusts the differential signals to render the output signal to enter a second state from the first state. Upon detecting the output signal having entered the second state, the control module stops providing the bias voltage and generates a disable signal to prompt the masking circuit to stop masking the output signal.

First claim

What is claimed is:

1. A receiver, for receiving a pair of differential signals provided by a transmitter, comprising:
a control module, configured to generate an enable signal and provide a bias voltage when a predetermined change occurs in the differential signals, the control circuit comprising a low-speed data receiving circuit that generates the enable signal;
a high-speed data receiving circuit, triggered by the enable signal to generate an output signal according to the d…
