The Analysis and Solution of a PLL Signal Source's Abnormity

Article Preview

Abstract:

In this paper, a kind of 120 kHz PLL signal source system is presented. Its based on the principle that changes in feedback voltage at a constant surge frequency which is related to reference voltage. At the same time, combine an actual test circumstance; the abnormity of signal lock is analyzed. Based the conclusion and the mode of interior parts, we take a simple adjust measure. The abnormity of the signal source is avoided availably.
