9 CXA3085AN description of functions the CXA3085AN is a ground wave broadcast tuner ic which converts frequencies to if in order to tune and detect only the desired reception frequency of vhf, catv and uhf band signals. in addition to the mixer, local oscillator and if amplifier circuits required for frequency conversion to if, this ic also integrates a pll circuit for local oscillator frequency control onto a single chip. the functions of the various circuits are described below. 1. mixer circuit this circuit outputs the frequency difference between the signal input to vhfin or uhfin and the local oscillation signal. 2. local oscillator circuit a vco is formed by externally connecting an lc resonance circuit composed of a varicap diode and inductance. 3. if amplifier circuit this circuit amplifies the mixer if output, and consists of an amplifier stage and low impedance output stage. 4. pll circuit this pll circuit fixes the local oscillator frequency to the desired frequency. it consists of a prescaler, main divider, reference divider, phase comparator, charge pump and reference oscillator. the control format supports the 3-wire bus format. the following four modes can be selected according to the combination of the frequency division values of the main and reference dividers. mode main divider reference divider a-0 15 bit 1024 fixed a-1 14 bit 512 fixed a-2 15 bit 640 fixed a-3/4 15 bit 512 fixed
10 CXA3085AN description of analog block operation (see the electrical characteristics measurement circuit.) vhf oscillator circuit this circuit is a differential amplifier type oscillator circuit. pin 18 is the output and pin 16 is the input. oscillation is performed by connecting an lc resonance circuit including a varicap to pin 18 via coupled capacitance, inputting to pin 16 with feedback capacitance, and applying positive feedback. pin 18 is an open collector, so power must be supplied via the resonance circuit inductance or by the resistance or microinductor. the electric potential of pin 18 at this time must be dc 3.5 v or more. the amplifier between pins 16 and 18 has an extremely high gain. therefore, care should be taken to avoid creating parasitic capacitance, resistance or other feedback loops as this may produce abnormal oscillation. vhf mixer circuit the mixer circuit employs a double balance mixer with little local oscillation signal leakage. the input format is base input type, with pin 12 grounded and the rf signal input to pin 13. the rf signal is inserted from the oscillator, converted to if frequency and output from pins 9 and 10. pins 9 and 10 are open collectors, so power must be supplied externally. the electric potential of pins 9 and 10 at this time must be dc 4.0 v or more. uhf oscillator circuit this oscillator circuit is designed so that two collector ground type colpitts oscillators perform differential oscillation operation via an lc resonance circuit including a varicap. an lc resonance circuit including a varicap is connected between pins 19 and 21. this circuit contains resonance capacitance comprising colpitts oscillators, so the lc resonance circuit connected to pins 19 and 21 oscillates at the frequency indicating the inductance characteristics. uhf mixer circuit this circuit employs a double balance mixer like the vhf mixer circuit. the input format is base input type, with pins 14 and 15 as the rf input pins. the input method can be selected from balanced input consisting of differential input to pins 14 and 15 or unbalanced input consisting of grounding pin 14 via a capacitor and input to pin 15. pins 9 and 10 are the mixer outputs. pins 9 and 10 are open collectors, so power must be supplied externally. the electric potential of pins 9 and 10 at this time must be dc 4.0 v or more. if amplifier circuit the signals frequency converted by the mixer are output from pins 9 and 10, and at the same time are ac coupled inside the ic and input to the if amplifier. single-tuned filters are connected to pins 9 and 10 in order to improve the interference characteristics of the if amplifier. the signal amplified by the if amplifier is output from pin 25. the output impedance is approximately 75 .
