Abstract

The invention provides a receiver circuit and a receiver circuit control method. The invention detects the input data through a detection circuit, obtains the data rate detection result, automatically adjusts the bandwidth of the receiver according to the data rate detection result, thereby avoiding the use of chip pins or information packets of the timing controller to control the bandwidth of the receiver, and realizes display The performance of the driver chip is optimized.

Description

Technical field [0001] The present invention relates to the technical field of receiver device, in particular to a receiver circuit and a receiver circuit control method. Background [0002] To support multiple types of application products, more and more display interface protocols cover a wide range of data rates. Receivers that support a wide range of data rates need to support these display interface protocols. In order to consume power efficiency, the receiver needs to set different bandwidths according to the data rate of different input data, where the greater the bandwidth required, the greater the current consumed. In the receiver, the Analog Front-End (AFE) will be confident that the small signal will be amplified into a large signal to clock data recovery circuitry (CDR). In general, there are two common ways to control the bandwidth of a receiver. One is to control it through the chip pin (PIN). The other is controlled by sending a package to the display driver chip v...
