Preliminary specification
SAB9076H
TEST AND APPLICATION INFORMATION
The application diagram for 1 FH mode in a standard
configuration is shown in Fig.10. Two input signals
MCVBS and SCVBS of different sources are processed by
the SAB9076H and inserted by the YUV/RGB switch.
The synchronization of the display PLL is derived from the
deflection circuit. The main signals are also fed to the
deflection circuit and the YUV/RGB switch where the
SAB9076H signals can be inserted. The signals for
deflection can also be taken from the main channel or
sub-channel decoder.
