Abstract

The invention relates to a serial transmission device, comprising a plurality of data transmission devices which are connected in series. Each data transmission device in serial connection comprises a multi-bit latch, a shifting cache and a switching module, wherein the multi-bit latch is used for providing parallel data, the shifting cache is used for receiving and outputting the parallel data to the multi-bit latch according to a bolt locking signal, and the switching module is used for providing a received data signal and a received time signal to the shifting cache, providing a latching signal to the multi-bit latch before a first clock period (containing a plurality of clocks) is finished after a synchronization signal is received as well as stopping providing of the latch signal to the multi-bit latch and providing a synchronization signal to a data transmission device of the next level before a second clock period is started.

Description

Technical field [0001] The invention relates to a transmission device, in particular to a serial transmission device. Background technique [0002] The communication transmission type between the controller and the peripheral device or the controller and the controller can be divided into parallel transmission communication (Parallel Communication) and serial transmission communication (Serial Communication). Among them, the serial transmission communication only needs three transmission lines (clock signal line, data signal line and latch signal line) at most to transmit and receive signals. The serial transmission method is a method of transmitting one bit of data through a clock signal, and sequentially transmits the input serial data to the connected transmission device. After the serial data is transmitted to each serially connected transmission device, a latch signal is used to latch and generate multiple parallel output signals. [0003] Serial transmission communication c...
