AN OSCILLATOR FREQUENCY CONTROL ARRANGEMENT FOR A STEREO DECODER |
摘要 |
<p>A charge pump arrangement (123) receives a digital error word (122a) representing an error signal and charges or discharges a capacitor (C4) in accordance with the sign of the error word by an amount that is proportional to the absolute value of the error word. The voltage produced in the capacitor (C4) is coupled to a frequency control terminal of a voltage controlled crystal oscillator (124) that is used in, for example, a stereo decoder.</p> |
