Oscillator

The oscillator frequency for the IR type of operation is twice the carrier frequency. Thus, the oscillator frequency

should be kept at 76kHz. A 430k~470k

Ω oscillator resistor between OSC1 and OSC2 pins is recommended. It

should be noted that the carrier is a 50% duty cycle frequency.
