FSK REF 1.4 V 0.7 V 1.2 V 1.4 V — 0.2 V Connects the external parts of crystal oscillator circuit. A capacitor and crystal oscillator are connected to these pins and VCC. Mixer output. Connect a 455 kHz ceramic filter between this pin and IF IN. Power supply. IF limiter amplifier input. Controls the battery saving. Setting this pin low suspends the operation of IC. (Applied voltage range: –0.5 V to +7.0 V) Connects the capacitor that determines the low cut-off frequency for the entire system. 2 1 VCC 300 15k 230 GND 72 15k 3 VCC GND 1.5k 5 VCC 1.5k GND 1.5k 8k 8k 6 72 40k 140k GND 7 VCC GND 72 |
