Abstract
A data transmission unit having a clock generating circuit for generating a continuous transfer clock signal which is always output from the data transmission unit regardless of presence or absence of transmission and reception; a data converter for converting parallel data to serial data; and a data transfer circuit for transferring the serial data in synchronism with the transfer clock signal. It can achieve the transmission of the serial data at high speed and with high reliability.
Claims12
A data transmission unit comprising:
- clock generating means for generating a continuous transfer clock signal which is always output from the data transmission unit regardless of presence or absence of transmission and reception;
- data converting means for converting parallel data to serial data;

A data transmission unit comprising:
- clock generating means for generating a continuous transfer clock signal which is always output from the data transmission unit regardless of presence or absence of transmission and reception;
- data converting means for converting parallel data to serial data;
- transmission start decision means for making a decision of a start of data transmission in response to said transfer clock and ready to accept information sent from a receiver;
- and
- data transfer means for transferring said serial data in synchronism with said transfer clock signal in response to a decision signal from said transmission start decision means.
