Abstract
A digital data transmission system for transmitting digital data, a frame pulse signal, and a clock using a required minimum number of signal lines and with a simple circuit structure is provided. A signal separation circuit ( ) that receives a multiple clock (CKFP) which is a frame pulse signal (FP) multiplexed with a clock (CK) includes a clock recovery circuit ( ) for reproducing a recovered clock (RCK) by synchronization with the multiple clock (CKFP) using a synchronization loop, and a frame pulse signal separation circuit ( ) for separating a recovered frame pulse signal (RFP) from the multiple clock (CKFP) on the basis of the recovered clock (RCK).
