  • Phase alignment of frames in computer telephony busses
    Patent number: 6219395
    Abstract: A communication bus interface circuit includes a local frame signal generator responsive to a device clock signal and having a local bus frame signal output. A synchronization loss detector is responsive to the local frame signal output and to a bus frame signal input. A clock adjuster is responsive to the synchronization loss detector and to the device clock signal to adjust the local frame signal generator until synchronization between the bus frame signal and the local frame signal is established.

  • Data phase recovery system
    Patent number: 6154509
    Abstract: Apparatus and method for processing serial data signals. In one general aspect, the method features receiving a first serial data signal having a clock frequency and phase, detecting a phase characteristic of the first serial data signal, and delaying the first serial data signal based on the phase characteristic of the first serial data signal to align at least one point in the first serial data signal with at least one point in a system clock signal.
