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

摘要

The system of claim 1 comprising a clock module configured automatic frequency correction to generate a first reference clock by using the (AFC) is provided that is not corrected. Global Positioning System (GPS) module is configured to receive a first clock reference. The integrated circuit for a cellular transceiver comprises a phase locked loop system, and the system is phase locked loop is configured to generate a second clock reference that receives the first reference clock, and performs the AFC, and the AFC and correction. ;
