Low-Power, High-Performance
NTSC/PAL Video Decoder
0X = Async mode or line-locked mode is set automati-
10 = PLL is forced to line-locked mode.
11 = PLL is forced to async mode.
When PLLBYP = 1, the ADC and the decoder use the
input crystal or clock (XTAL/OSC, XTAL2) directly.
1 = Bypass the PLL.
0 = PLL is enabled (default).
Disable the digital anti-aliasing filter following the ADC.
1 = Disables filter.
0 = Enables filter (default).

PLLBW controls a digital loop filter that sets the band-
width of the line-locked PLL.
