Case #1: Normal operation
Register 9, bit1=0
Case #2: Soft Blanking mode
Register 9, bit1=1
Specific application conditions
To simplify the application, it is possible to supply the power V
at the expense of output swing voltage.The CRT Heater voltage (6.2V Typ.) is used very often to
supply V
If no blanking pulse is applied to the STV9211, it is necessary to ensure the OCL pulse generation
(which sets the infra-black level) by setting the Register 8, bit7=1 (OCL = BPCP).
To ensure the device correct behavior in the worst possible conditions, the brightness Register must
be set to 0.
It is possible to blank the video signal by setting the Register 9, bit1=1 and Register 8, bit 6=1.
In this mode the output voltage is set to Vib (see
changing the timing resolution of the video, in order to suppress the video during this transient
period.
