Product Specifications

Technical details and manufacturing context for Multiplexer (MUX) / Shift Register

Definition
Within a Serializer (Parallel-in Serial-out) system, this component serves as the core data processing unit. It first multiplexes multiple parallel input channels into a single data stream, then uses shift register functionality to sequentially output the data in serial format, enabling efficient data transmission and interface conversion.
Working Principle
The component operates by first selecting between multiple parallel input lines using multiplexer logic based on control signals. The selected parallel data is then loaded into a shift register, where clock signals control the sequential shifting of bits from the parallel register to a single serial output line, converting parallel data to serial format.
