H-PLL Response Time
When in the Normal mode, the horizontal PLL (H-PLL) response time is set to its slowest setting. This mode improves noise
immunity and provides a more stable output line frequency for standard TV signal sources (for example, TV tuners, DVD players,
video surveillance cameras, etc.).
When in the Fast mode, the H-PLL response time is set to its fastest setting. This mode enables the H-PLL to respond more
quickly to large variations in the horizontal timing (for example, VCR head switching intervals). This mode is recommended for
VCRs and also cameras locked to the AC power-line frequency.
When in the Adaptive mode, the H-PLL response time is automatically adjusted based on the measured horizontal phase error. In
this mode, the H-PLL response time typically approaches its slowest setting for most standard TV signal sources and approaches
its fastest setting for most VCR signal sources.
