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.
