Working Principles

The TRSF3222EIDWR is a dual-channel serial transceiver that enables bidirectional communication between two devices. It operates by converting parallel data from the transmitting device into serial data for transmission over a communication line. On the receiving end, it converts the received serial data back into parallel format for use by the receiving device. The transceiver supports full-duplex communication, allowing simultaneous transmission and reception.
