The MII is transmitted to the MII reception data system control unit 401 in units of 4 bits synchronized with the synchronous synchronization. In the case of receiving an invalid symbol, the MII reception error signal is transmitted to the system control unit 401. When transmission and reception occur simultaneously and a collision occurs, the MII collision signal is transmitted to the system control unit 401. Do this.

When receiving a carrier (carrier) performs a function to deliver the MII carrier reception signal to the system control unit 401, and if a transmission error occurs, receives the MII transmission error signal from the system control unit 401. In addition, when the operation mode of the 10 Mbps HomePNA modulation and demodulation processing unit 1101 is set, the system control unit 401 receives MII management data synchronized with the MII management data clock. Performs QAM / FDQAM modulation function on the received MII transmission data.

In addition, it performs a function of delivering a DAC signal to the 10Mbps HomePNA AFE processing unit 1102, receives the ADC signal from the HomePNA AFE processing unit 1102, performs a QAM / FDQAM demodulation function to receive the MII received data system control unit 401 To pass.

In addition, the HomePNA AFE processing unit 1102 receives the DAC signal from the HomePNA modulation and demodulation processing unit 1101 and converts the signal into an analog signal, and transmits the HomePNA transmission signal to the home network through the two-line telephone line. Receives an analog signal HomePNA received signal from the home network through the telephone line to convert the digital signal and transmits the ADC signal to the 10Mbps HomePNA modulation and demodulation processing unit (1101).

The detailed description and drawings of the present invention disclose a preferred embodiment for the purpose of understanding the present invention, and do not limit the scope of the present invention. The scope of the present invention is determined by the above detailed description. Rather, it should be determined in the appended claims.
