Problems solved by technology

[0004] The purpose of the present invention is to propose a BMC transmitter, to solve the traditional BMC transmitter in the prior art and the existing BMC receiver module are different in circuit properties, resulting in the mutual influence of digital modules and analog modules on the power supply system , At the same time, because the traditional BMC transmitter's equally spaced data or clock drive is a digital buffer, it will not only bring a large power switching noise, but also consume a large chip area and power consumption

Abstract

The invention discloses a BMC transmitter. Through a current-type digital-to-analog converter, under the control of a delay control unit, the data sent by the data encoding and protocol processing unit are delayed at equal intervals, and then the current-type digital-analog converter is controlled. The digital-to-analog converter charges and discharges the RC circuit to obtain a precisely controlled conversion time, and then drives the data with the controlled conversion time to the CC channel through the unit gain buffer to generate an output waveform. The present invention solves the problems in the prior art. The traditional BMC transmitter module is different from the BMC receiver module in terms of circuit properties, resulting in the mutual influence of digital modules and analog modules on the power system. , the power switching noise brought about, and the problem of consuming a large chip area and power consumption.

Description

technical field [0001] The present invention relates to the technical field of circuit design, in particular to a BMC transmitter. Background technique [0002] At present, Type-C, as an emerging USB (Universal Serial Bus, Universal Serial Bus) interface standard, with the support of the USB-PD protocol, can provide higher data transmission speed, higher power online power supply capability and more Simple and lightweight system connection, and supports USB3.1 data and includes DP (DisplayPort, high-definition digital display standard interface), HDMI (High Definition Multimedia Interface, high-definition multimedia interface) and MHL (MobileHigh-Definition Link, mobile terminal high-definition audio and video) Simultaneous transmission of a variety of video data, including standard interface), etc. According to the USB-PD specification, the connection between the upstream and downstream devices of Type-C is completed by using the BMC (Biphase Mark Coding, biphase coding) c...
