PROBLEM TO BE SOLVED: To provide a satellite-mount digital unit that can flexibly adjust its interface for a plurality of different satellite projects. SOLUTION: The satellite-mount digital unit is provided with digital circuits 101-10n that conduct specific processing in a satellite mount device and an interface processing circuit 110 that conducts interface processing with other device or the like. A transformer 12 applies a common voltage to the digital circuits 101-10n and the interface processing circuit 110 via a power supply filter 13. The interface circuit 110 is provided with an interface circuit having an interface function with other device and with a DC-DC converter 111 that generates an exclusive voltage required for the interface circuit from the common voltage. |
