TEMPERATURE COMPENSATED PLL CALIBRATION

摘要

In some embodiments, provided are AFC circuits and methods for calibrating a second setting of an oscillator while a first setting is controlled by a temperature compensated control.

主权项

1. A chip, comprising:
an oscillator with first and second settings for controlling an output frequency; a temperature compensated circuit to provide the first setting based on a chip temperature during a calibration mode; and calibration logic to adjust the second setting until the output frequency is sufficiently close to a target frequency during the calibration mode.
