CVBS levels with default settings RAWG[7:0] = 64 and RAWO[7:0] = 128.
Equation for modification of the raw data levels via bytes RAWG and RAWO:
It should be noted that the resulting levels are limited to 1 to 254 in accordance with “

YNCHRONIZATION
The prefiltered luminance signal is fed to the synchronization stage. Its bandwidth is further reduced to 1 MHz in a
low-pass filter. The sync pulses are sliced and fed to the phase detectors where they are compared with the sub-divided
clock frequency.The resulting outputsignal is appliedto the loopfilter toaccumulate all phase deviations.Internalsignals
(e.g. HCL and HSY) are generated in accordance with analog front-end requirements. The loop filter signal drives an
oscillator to generate the line frequency control signal LFCO; see Fig.21.
The detection of ‘pseudo syncs’ as part of the Macrovision copy protection standard is also achieved within the
synchronization circuit.
The result is reported as flag COPRO within the decoder status byte at subaddress 1FH.
