专利汇可以提供Start bit detection circuit专利检索,专利查询,专利分析的服务。并且PURPOSE: To attain the data transmission without taking notice of the data fetch system at the receiver side and the state of line by setting number of times of start bit sampling externally with respect to the start bit detection circuit at the receiver side of the transmission data.
CONSTITUTION: A trailing edge detection circuit 1 detects a trailing edge of a start bit. An output of the trailing edge detection circuit 1 starts a counter 3, from which the count by a clock for the start bit is outputted. A selector 4 able to select an optional value through external setting selects the count outputted from the counter 3 to be a desired value. A one-shot circuit 5 outputs the output of the selector 4 by one clock. A comparator circuit 2 compares the output of the one-shot circuit 5 with the sample of the start bit and when the both are coincident, no operation is implemented and when the both are dissident, the counter 4 is stopped.
