Abstract
A phase locked loop (PLL) chain for locking audio sampling to serial digital component video timing has a deserializer that recovers a video sample clock signal from a serial digital video signal, the deserializer including a wide bandwidth PLL. A tracking filter in the form of a narrow bandwidth PLL having a low pass filter function reduces the jitter in the video sample clock signal to produce a stable reference clock signal. The stable reference clock signal is input to an audio sample clock generator to produce a stable audio sample clock signal for extracting audio data from the serial digital video signal.
