Fig.7 Typical VIF and tuner AGC characteristic.

(1) VVAGC is VIF-AGC voltage and can only be measured at pin OP2 controlled by the I2C-bus (see Table 15).

(2) ITAGC is tuner current in TV mode with RTOP =22kΩ or setting via I2C-bus at −15 dB.

(3) ITAGC is tuner current in TV mode with RTOP =10kΩ or setting via I2C-bus at 0 dB.

(4) ITAGC is tuner current in TV mode with RTOP =0kΩ or setting via I2C-bus at +15 dB.
