Application Circuit Notes
1. RF output pin 24 should be connected to a 75Ω load in oder to measure accurate input level. Also note pin 24
has 2.7kΩ to GND.
The output is measured using a spectrum analyzer.
2. After turning the device on, tune the variable inductor FM Tank so at the 6.5MHz setting (set by I2C control)
the voltage on pin 6 should read 2.02V.
Set Fsound = 3
Delta Fsound = 1
