Notes:1. The voltage applied as the digital system power supply voltage must not exceed the voltage applied as the analog system power supply voltage.
2. Unused input pins must be tied high or low. If the OSD inputs are not used, tie OSBLK (pin 39) low.
3. Note that the clock input frequencies (CLKI: pin 6, and FSCIN: pin 7) depend on the TV subcarrier pull-in range. The CLKI input clock and the
FSCIN clock must be synchronized.
