BMC PROCESSING CIRCUIT, USB POWER DELIVERY CONTROLLER, BMC RECEPTION METHOD, AND NON-TRANSITORY COMPUTER READABLE MEDIUM STORING BMC RECEPTION PROGRAM

摘要

A BMC processing circuit, a USB power delivery controller, a BMC reception method, and a program capable of achieving stable BMC reception processing with low power consumption are provided. A BMC processing circuit 1100 includes an edge detection unit 1102 that detects change edges of a reception signal encoded by a Biphase Mark Code (BMC) method; an interval measuring unit 1103 that measures an interval value, the interval value being a period between the change edges; a threshold determination unit 1105 that corrects a first threshold using a plurality of interval values to generate a second threshold; and a BMC decoding unit 1107 that decodes the reception signal using the second threshold.
