Description
automatic field detection
field selection
forced ODD/EVEN toggle
horizontal time constant selection
horizontal PLL
vertical noise reduction
Description
chrominance trap bypass
prefilter active; see
aperture band-pass (center frequency)
0 = field state directly controlled via FSEL
1 = automatic field detection
0 = 50 Hz, 625 lines
1 = 60 Hz, 525 lines
0 = ODD/EVEN signal toggles only with interlaced source
1 = ODD/EVEN signal toggles fieldwise even if source is non-interlaced
00 = TV mode (recommended for poor quality TV signals only; do not use for new
applications)
01 = VTR mode (recommended if a deflection control circuit is directly connected to
SAA7144HL)
10 = reserved
11 = fast locking mode (recommended setting)
0 = PLL closed
1 = PLL open; horizontal frequency fixed
00 = normal mode (recommended setting)
01 = fast mode [applicable for stable sources only; automatic field detection (AUFD) must be
disabled]
10 = free running mode
11 = vertical noise reduction bypassed
0 = chrominance trap active; default for CVBS mode
1 = chrominance trap bypassed
0 = bypassed
1 = active
00 = center frequency is 4.1 MHz
01 = center frequency is 3.8 MHz; see
10 = center frequency is 2.6 MHz; see
11 = center frequency is 2.9 MHz; see
