Note) Tuning is taken the peak point at 10.6 MHz output level ( VIN = 30 dBµ, non-modulation)
*1 : Conversion gain = 20 Log( ∆V (µV) ÷ 31.6)
∆V is the output difference at VIN = 30 dBµ and at VIN = 36 dBµ
*2 : Measurement is done at the detection output of the AN7233
Measure the ratio of output at fDIV = 22.5 kHz to that at fDIV = 0 Hz (modulation freq. 1 kHz)
