Why UART Serial Communication Requires 16x Oversampling

Why UART Serial Communication Requires 16x Oversampling

Enhancing anti-interference is one reason. Standard UART can choose 16x sampling or 64x sampling; I personally think it should be for convenient frequency division design. The RXD front end of the standard UART has a “1 to 0 transition detector.” When it continuously receives 8 ground level signals on RXD, the detector considers that the … Read more
