Abstract
A biphase mark coding transmitter is provided. In the biphase mark coding transmitter, a delay control unit performs equal-interval delay processing on data transmitted by a data coding and protocol processing unit. Then, the current-steering digital-to-analog converter is controlled to charge or discharge a resistance-capacitance circuit to obtain an accurately-controlled conversion time. Data with the controlled conversion time is driven to a CC by a unity-gain buffer to generate an output waveform. The technical solution solves the technical problem of a mutual influence between power source systems of a traditional BMC transmitter which is a digital module and a traditional BMC receiver which is an analog module, and the technical problem of a large noise of a power switch and large consumption of chip area and power which are resulted from digital buffers driven by equal-interval data or clocks in a traditional BMC transmitter.
