Chip adopts PHY to dock（Network interface directly docks）Mode connect it is achieved that data forwarding link, the periphery of WIFI master chip is joined
There are internal memory and flash memory cell, wireless and Ethernet interface, the I/O pin simulation MDC/MDIO bus of WIFI master chip, make
For controlling and managing the controlling bus of MoCA master chip, the CPU of WIFI master chip controls and management MoCA master chip, realizes opening
The items such as dynamic, monitoring MoCA master chip work, the flash memory cell of WIFI master chip periphery preserves the program of MoCA master chip
And configuration.
Due to the switch in conventional techniques or PHY chip be substituted for using WIFI master chip, need not recycle outer
The Micro-processor MCV put just can realize control and the management of MoCA master chip, reduces hardware cost, meanwhile, the main core of WIFI
The wireless and Ethernet interface of piece periphery, solves the demand that radio and TV operator surfs the Net for MoCA terminal wireless.
Fig. 3 is the theory diagram of the second embodiment of the present invention, except between WIFI master chip and MoCA master chip
Connected mode different outer, remaining is essentially identical with the principle of the first embodiment.As shown in figure 3, WIFI master chip with
The setting MII interface on WIFI master chip that connects through of MoCA master chip adopts MII bus to connect, and realizes data forwarding chain
Road.
