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.
Power save
0 = Normal operation (default)
1 = Power save mode. Reduces the clock speed of the internal processor and switches off the ADCs. I2C interface is active and all
current operating settings are preserved.
