2 / 30 page – 2 – CXA3117N Pin Description Pin No. 1 1.4V 0.7V 1.3V 1.4V — 0.2V OSC IN Connects the external parts of crystal oscillator circuit. A capacitor and crystal oscillator are connected to these pins and VCC. Mixer output. Connect a 455kHz ceramic filter between this pin and IF IN. IF limiter amplifier input. Determines the level comparator threshold value. Threshold value can be adjusted by inserting the resistor between Pin 6 and VCC. Normally, short to VCC. Connects the capacitor that determines the low cut-off frequency for the entire system. Power supply.
