Measure RF level by spectrum analyzer (Input impedance=50) and calculate
measurement data Vo (dBm) by
Output Level (dBp1/)=1/o+ 107+ 16 (dBp1/)
Measure after that demodulated by the standard demodulator (For example
Tektronix 1450).
Adjust a sound FM center frequency to 4.500MHz at Ta =25°C, then measure a
frequency drift at Ta =0~60°C for at Ta = 25°C.
This spec (Afs) does not include TANK temperature coefficiency.
Connect Va+0.2 (V) and Va-0.2 (V) to V1 (Va , #6 terminals open voltage) then
measure each frequency and calculate by
[35: Frequency difference between V1=Va+0.2 and 1/2=Va-0.2
Adjust Vi2 level so that FM deviation become -+20KHz, then measure THD after
that demodulate by standard demodulator (for example tektronix 1450)

HANDLING PRECAUTIONS
l. The device should not be inserted into or removed from the test jig while the voltage is being
applied: otherwise the device may be degraded or break down.
Do not abruptly increase or decrease the power supply to the device either.
Overshoot or chattering of the power supply may cause the IC to be degraded.
To avoid this filters should be incorporated on the power supply line.
2. The application circuits described in this datasheet are given only as system examples for
evaluating the device's performance. Toshiba Intend neither to recommend the configuration or
related values of the peripheral circuits nor to manufacture such application system in large
quantities.
Please note that high-frequency characteristics of the device may vary depending on the external
components, mounting method and other factors relating to the application design.
Therefore, the characteristics of application circuits must be evaluated at the responsibility of the
users incorporating the device into their design.
Toshiba only guarantee the quality and characteristics of the device as described in this detasheet
and do not assume any responsibility for the customers application design.
3. In order to better understand the quality and reliability of Toshiba semiconductor products and
to incorporate them into design in an appropriate manner, please refer to the latest
Semiconductor Reliability Handbook (Integrated Circuit) published by Toshiba Semiconductor
Company.
