Table 17 Frequency selection bits
Notes
1. Pin SIOMAD can be used for the selection of the different NTSC standards without I2C-bus. With a resistor on
pin SIOMAD, the fVIF = 58.75 MHz and without a resistor on pin SIOMAD, the fVIF = 45.75 MHz (NTSC-M).
2. Attention: video sound traps are locked on the FM VCO. The second VIF should be selected in accordance with the
selected video standard.
