Abstract

A system and methods are provided for calibrating timing in a remote device (120) to timing in a source device (110). The source device (110) dictates timing signals to be generated in the remote device (120). A calibration routine (510-540) is processed to calibrate timing in the remote device (120) to timing in the source device (110). The source device (110) provides a reference signal (119) that dictates a period of time to the remote device (120). The remote device (120) tracks a number of local clock cycles generated for the duration of the dictated period of time. The remote device then establishes a time base for translating a number of clock cycles dictated by the source device (110) to a number of clock cycles generated within the remote device (120).
