  • Publication number: 20180294998
    Abstract: A video signal and an audio signal are TMDS transmitted from a source device to a sink device. Through a reserved line and a HPD line provided separately from a TMDS transmission line, an Ethernet™ signal is bidirectionally transmitted, and also, a SPDIF signal is transmitted from the sink device to the source device. The Ethernet™ signal bidirectionally transmitted between Ethernet™ transmitter/receiver circuits is differentially transmitted by an amplifier and is received by the amplifier. The SPDIF signal from a SPDIF transmitter circuit is common-mode transmitted from an adder and is received by the adder to be supplied to the SPDIF receiver circuit.

  • Patent number: 10018680
    Abstract: A semiconductor device, a battery monitoring system, and a method for activating the semiconductor device that may reduce current consumption in standby state. An integrated circuit (IC) of the semiconductor device includes an activation circuit that uses a ground of the IC as ground and a power source voltage of the IC as its power source, and a driving circuit that uses the power source voltage as ground and a boosted voltage output from a boosting circuit as its power source. In the IC, only the activation circuit enters an operation state in a standby state, and when recovered from the standby state, causes the activation circuit to make inner circuits of the IC enter the operation state based on an activation signal. When all the inner circuits enter the operation state, the driving circuit outputs the activation signal to the activation circuit of an upper IC.
