3 / 12 page —3— CXA1851N Typical pin voltage (V) 10 MIX OUT1 2.3 MIX output pin for the up converter. 11 MIX OUT2 2.3 MIX output pin for the up converter. Connect an approxi- mately 4.7 nH chip inductor and an approximately 3.5 pF chip capacitor between this pin and Pin 10 to form a tank circuit. 12 GND 0.0 GND pin for the oscillator buffer amplifier and mixer blocks of the up converter. 13 IF BYPASS 1.03 IF input by-pass pin for the up converter. 14 IF INPUT 1.03 IF input pin for the up converter. Because of high impedance, an external matching circuit is necessary which consists of a 220 nH chip inductor and an approximately 1.5 pF chip capacitor. 15 OSC INPUT 1.8 Oscillator input pin for the up (for UP converter. A matching circuit CONV.) consisting of a 51 Ω resistor is necessary. 16 OSC 1.8 Oscillator input by-pass pin for the BYPASS up converter. (for UP CONV.) 17 OSC 1.85 Oscillator input by-pass pin for the BYPASS down converter. (for DOWN CONV.) 18 OSC 1.85 Oscillator input pin for the down BYPASS converter. A matching circuit (for DOWN consisting of a 51 Ω resistor is CONV.) necessary. 19 Vcc 2.7 to 4.5 Power supply for the down (for DOWN converter. CONV.) 20 IF OUTPUT 1.45 IF output pin for the down converter. 10 11 REG 13 14 15 16 17 18 20 Pin No. Symbol Equivalent circuit Description |
