Power supply circuit for IEEE 1394 interface |
摘要 |
A power supply circuit for IEEE 1394 interface includes an IEEE 1394 interface control chip, an interface circuit, and a power circuit. The IEEE 1394 interface control chip outputs transmission protocol signals. The interface circuit is electrically connected to the IEEE 1394 interface control chip by a number of differential signal transmission lines. The interface circuit receives the transmission protocol signals and exchanges data with a peripheral device according to the received transmission protocol signals. The power circuit has a voltage decreasing circuit and provides working voltage to the interface circuit. The voltage decreasing circuit receives a DC voltage and converts the received DC voltage to the working voltage. |
