CRT cathode, DC-coupling mode (
The STV9211 can be used in DC coupling mode only.
The cut-off (InfraBlack) adjustment is done by the preamplifier.
The infra-black level (Vib) is adjusted independently for each channel via the Registers 10, 11 and
12 (see the complete description in
Preamplifier stand-by mode
The STV9211 is set in stand-by mode either by I
In stand-by mode, the analog blocks are internally switched-off while the logic parts (I
power-on reset) are still supplied.
The power consumption is below 20mW.
Amplifier stand-by mode
The STV9211 can set in stand-by mode any ST video amplifier with the CTL control pin.
When Register 9, bit 7=1, the AMPCTL pin is switched to low level (<0.3V). The amplifier is set in
stand-by mode when CTL<0.3V.
If not used, the AMPCTL pin must be connected to ground.
