SERDES is an acronym for english Serializer. It is a mainstream serial communication technology of parallel-to-serial conversion and point-to-point (P2P). I.e. multi-path parallel (note: parallel is a relative concept here and not limiting the format of the video signal) signals are converted into high-speed serial signals at the transmitting end, via the transmission medium (coaxial or twisted pair), and finally the high-speed serial signals are reconverted into parallel signals at the receiving end. The point-to-point serial communication technology fully utilizes the communication speed of a transmission medium, reduces the number of required transmission lines and the number of pins of a device, and improves the transmission speed of signals, thereby greatly reducing the communication cost. Namely, the serializer can convert the multipath parallel signals into serial signals; the deserializer may convert the serial signal to a parallel signal. The daisy chain connector drives the display device in a cascade fashion.
