■ FSK WAVE SHAPING FUNCTION
■ QUICK CHARGE / DISCHARGE FUNCTION
state turns into the ordinary state, the FSK-REF terminal voltage will be late to come up to the reference voltage by the
time constant of an external capacitor and an internal resistor, and the wave shaped data may be failed. This circuit will
charge/ discharge the external capacitor quickly to prevent the error.
terminal voltage follows to the FSK demodulated output DC voltage, and the FSK output duty ratio can be constant.
■ APPLICATION CIRCUIT
Ver.2003-12-09
When the demodulated FSK signal is weak or noisy, the micro computer may fail to read data.
The wave shaping circuit (comparator) will change those signals to the correct logical signal to prevent the readerror.
The DC voltage of the FSK-REF terminal is equal to that of the demodulated FSK signal. When the battery saving
When the DC level of the FM demodulated output changes in the operation mode of this function, the FSK-REF
