Abstract

The invention discloses a hybrid transmitting end driver and an application method thereof, relates to the technical field of high-speed interface transmitting circuits, and can adapt to different scene modes to configure low power consumption of a transmitting circuit and flexibly configure source end impedance, swing and common mode range. According to the main technical scheme, the driver comprises a mode selection module, an impedance configuration module and a low-voltage source configuration module, control signals are sent to the three modules according to a target signal value set corresponding to a target scene mode, and due to the fact that signal values are pre-assigned to different switches and are used for representing the on or off of the control switches, the control signals are transmitted to the mode selection module, the impedance configuration module and the low-voltage source configuration module. Therefore, the switch-on or switch-off of the switches in the respective circuit connection structures of the three modules is controlled, and the flexible configuration is that a push-pull current mode or a voltage driving mode is selected to be switched on, a source end matching resistor is selected to be switched off or switched on, and particularly, different low-voltage sources can be adaptively selected in a VM mode so as to achieve the required swing and common mode range.

Description

Hybrid transmitter driver and application method thereof technical field The present invention relates to high-speed interface transmission circuit technical field, relate in particular to a kind of hybrid transmitter and its application method. Background technique [0002] A driver (DRV) broadly refers to the driving physical hardware (PHY) that drives a certain type of device, such as a liquid crystal display The driver in the timing controller (TCON) chip of the monitor, and the driver of the TV master system-on-chip (SOC) display interface devices, USB hosts, drivers for peripheral controllers, etc. Fig. 1 is the impedance matching schematic diagram of the receiver terminal, in Fig. 1 shows the positive end (TXP) of the transmitting end, the transmitting end The negative terminal (TXN), termination requires impedance matching (Rterm) and receiver termination (RX). Suitable for receiver terminal shown in Figure 1 (RX) matching resistance (Rterm), the tradition...
