* Culprits oscillation circuit is used in this IC as a crystal oscillation circuit. Caution is required for layout of the board
because oscillation between pin25 and power source and GND line.
* The margin of crystal oscillation changes due to the combination of the IC, a crystal oscillator and a board layout. This
independent IC does not quarantine the oscillation operation.
* This IC uses the signal of FM band frequency (VCO divided into 1/4) which leaks into ANT pin. If the VCO leakage
affects the performance of the system, make sure to connect an isolator on ANT pin path.
