SYNCHRONIZING SERIAL TRANSFER SYSTEM

摘要

PURPOSE:To improve the transfer efficiency by retarding a serial data from a data transmission side by 1/2 clock period, transferring the result to a data reception side so as to quicken the data latch timing at the data reception side. CONSTITUTION:A data 11 to be sent in a data transmitter 1 is loaded in a shift register 7 as a parallel data and transferred to a re-timing device 3 via a data line 4 as a serial data. The serial data is transferred to a data receiver 2 via a data line 5 while it is retarded by 1/2 clock. Then it is possible to fetch the serial data at the leading faster than the trailing of the clock signal by 1/2 clock period at the data receiving side. Thus, the transfer efficiency is improved.
