TWO-STAGE DATA SERIALIZATION
This abstract first appeared for US patent application 18934506 titled 'TWO-STAGE DATA SERIALIZATION
Original Abstract Submitted
A transmission driver for serial communication includes first multiplexing circuitry configured to partially serialize a data group into data subgroups based on an in-phase clock, and to delay a quadrature clock corresponding to the in-phase clock. The delay is based on latency of the partial serialization. The transmission driver also includes second multiplexing circuitry having a source-series terminated (SST) driver configured to serialize the data subgroups into a serial data stream based on the delayed quadrature clock. The first multiplexing circuitry may be configured to partially serialize the data group into the data subgroups by arranging a four-bit data group into a pair of two-bit data groups, and the second multiplexing circuitry may be configured to serialize the data subgroups into the serial data stream by arranging the pair of two-bit data groups into the serial data stream.
