  • Differential driver with common mode voltage tracking and method
    Patent number: 8363705
    Abstract: In a transceiver, a transmitter circuit is provided substantially the same common-mode voltage regardless of whether the transceiver is in a transmitting or receiving mode. In one embodiment, the transmitter circuit includes a driver circuit which, in the transmission mode of the transceiver, drives an output differential signal, and which, in the receiving mode of the transceiver, provides a termination circuit for an input differential signal. A variable resistor is provided to connect between a supply voltage and the driver circuit, the resistance of the variable resistor is selected such that the common-mode voltage of the output differential signal of the transmission mode substantially equals the common-mode voltage in the input differential signal of the receiving mode.

  • Bidirectional communication protocol between a serializer and a deserializer
    Patent number: 8332518
    Abstract: A method provides a bidirectional communication protocol for data communication between a first device and a second device. The method includes: during a first time interval, transmitting data from the first device to the second device; and during a second time interval, (a) after the occurrence of a first event, (i) suspending data transmission from the first device to the second device; and (ii) transmitting control data from the second device to the first device; and (b) after the occurrence of a second event, transmitting control data from the first device to the second device.
