Abstract:
1. A serial type interface circuit for transmitting/receiving data via a serial interface, comprising: an analog circuit connected to a serial line for analog-processing transmission/reception signals of the serial line; a digital circuit connected to said analog circuit for digital-processing the received signals from said analog circuit and the transmission signals to said analog circuit according to clocks; a clock generation circuit for supplying said clocks to said digital circuit; and a gate circuit for supplying the clocks of said clock generation circuit to said digital circuit and stopping the supply of the clocks simultaneously with cut of the power of said analog circuit according to a power save instruction, wherein said analog circuit includes: a driver to said interface; a receiver from said interface; a detection circuit for detecting a burst signal of said interface; and a clock generation source for generating clocks synchronizing with the signals of said interface, and wherein said digital circuit returns said gate circuit to the clock supply status according to a frame transmission request that said detection circuit detected from the burst signal.
