VOICE-CHANNEL FREQUENCY SYNCHRONIZATION |
摘要 |
A synchronized frequency generating system (100) comprises a main crystal clock (102), for producing a basic frequency FB, a channel sampling phase locked loop (PLL) unit (104) connected to the main crystal clock, for converting the basic frequency FB into a channel sampling frequency FCS, a voice sampling PLL unit (108) connected to the main crystal clock (102), for converting the basic frequency FB into a voice sampling frequency FVS, a time tracking unit (106) connected to the channel sampling PLL unit (104), for detecting signal characteristics so as to determine a channel sampling frequency phase change value and a frame timing phase change value, and a phase controller (110) connected to the voice sampling PLL. The phase controller (110) receives channel sampling frequency phase adjustment data and determines a voice sampling frequency phase change value. The phase controller (110) provides the voice sampling frequency phase change value to the voice sampling PLL.
