SYSTEM AND TRANSCEIVER CLOCKING TO MINIMIZE REQUIRED NUMBER OF REFERENCE SOURCES IN MULTI-FUNCTION CELLULAR APPLICATIONS INCLUDING GPS

摘要

A system comprises a first clock module configured to generate a first clock reference that is not corrected using automatic frequency correction (AFC). A global position system (GPS) module is configured to receive the first clock reference. An integrated circuit for a cellular transceiver includes a system phase lock loop configured to receive the first clock reference, to perform AFC, and to generate a second clock reference that is AFC corrected.
