TEST CONDITION (VCC = 9V, Ta = 25Â±3Â°C)

MEASUREMENT METHOD

(1) Apply the signal (f0 = 4.5MHz, fm = 400Hz, 25kHz / devi FM, 100mVrms)

to pin 52.

(2) Measure the output signal amplitude pin 54.

(1) Same as Note 22 (1)

(2) Measure the distortion of output signal at pin 54.

(1) Apply the signals as follows to pin 52,

FM : 400Hz 25kHz / devi FM, 100mVrms

AM : 400Hz 30% 100mVrms

(2) Measure the output level at pin 54 against each input.

AMR = 20âog (FM / AM)

(1) Same as Note 22 (1)

(2) Change the input level. Measure the input level when the output level at pin 54

become â3dB.

(1) Same as Note 22 (1)

(2) Change the input frequency. Measure the input frequency when the output level

at pin 54 become â3dB compare with peak level.

Measure the output impedance at pin 54.
