Preliminary specification
Infrared remote control transmitter
(RECS 80 low voltage)
SAA3008
Oscillator
(OSCI, OSCO)
The external components for the oscillator circuit are connected to OSCI and OSCO. The oscillator operates with a
ceramic resonator in the frequency range 350 kHz to 500 kHz, as defined by the resonator. When operating at a supply
voltage of below 3 V a 270 kHz resistor should be connected in parallel with the resonator.
