Abstract:
An information transmission system comprising:an information transmission section; andan information receiving section;whereby information can be serially transmitted from said information transmission section to said information receiving section;said system further comprising;a single clock signal line connecting said information transmission section and said information receiving section;a clock generating section for generating a clock signal sent to said clock signal line;a first frequency dividing section for dividing said clock signal supplied from said clock generation section by a value formed by multiplying said information to be transmitted from said information transmission section to said information receiving section, by even-number;a second frequency dividing section for dividing an inverted clock derived from said clock signal by a value formed by multiplying said information to be transmitted from said information transmission section to said information receiving section, by even-number;a synthesizing section for synthesizing an XOR signal from the output signals from said first and second frequency dividing sections; anda frequency divisor detection section, disposed in said information receiving section, whereby the time interval formed between successive periods at which a level of said output signal output from said signal synthesizing section is changed at the rising edge of the clock signal, is measured, thereby detecting the value set in the first frequency dividing section, and the time interval formed between successive periods at which a level of said output signal output from said signal synthesizing section is changed at the falling edge of the clock signal, is measured, thereby detecting the value set in the second frequency dividing section.
