Integrated transmission circuit and method

An integrated transmission circuit, for transmitting output data via a transmission interface, the integrated transmission circuit comprising:

• a first application circuit, for receiving and processing first data to output first processed data;
• a second application circuit, for receiving and processing second data to output second processed data;
• a media access control (MAC) circuit, coupled to the first application circuit and the second application circuit, for encoding the first processed data and the second processed data so as to output encoded data;
• and
• a physical layer (PHY) circuit, coupled to the MAC circuit to receive the encoded data so as to output the output data to the transmission interface;
• wherein the first application circuit and the second application circuit have different functions;
• and the MAC circuit interactively encodes the first processed data and the second processed data so as to output the encoded data to the PHY circuit.
