PIN FUNCTION DESCRIPTION
These pins form the PLL reference oscillator when connected to an external
parallel–resonant crystal (10.24 MHz typical). The reference oscillator is also the
second Local Oscillator (LO 2 ) for the RF receiver.
Voltage Regulator output pin. The internal voltage regulator provides a stable power
supply voltage for the R x and T x PLL’s and can also be used as a regulated supply
voltage for the other IC’s.
Three state voltage output of the R x Phase Detector. This pin is either “high”, “low”,
or “high impedance” depending on the phase difference of the phase detector input
signals. During lock, very narrow pulses with a frequency equal to the reference
frequency are present. This pin drives the external R x PLL loop filter. It is important
to minimize the line length and capacitance of this pin.
Ground pin for PLL section of IC.
Three state voltage output of the T x Phase Detector. This pin is either “high”, “low”,
or “high impedance” depending on the phase difference of the phase detector input
signals. During lock, very narrow pulses with a frequency equal to the reference
frequency are present. This pin drives the external T x PLL loop filter. It is important
to minimize the line length and capacitance on this pin.
Expander rectifier filter capacitor pin. Connect capacitor to V CC .
Transmit divide counter input which is driven by an ac coupled external transmit
loop VCO. The minimum signal level is 200 mV pp @ 80.0 MHz. This pin also
functions as the test mode input for the counter tests.
Microprocessor serial interface input pins for programming various counters and
control functions.
Microprocesor Clock Output which is derived from the 2nd LO crystal oscillator and
a programmable divider. It can be used to drive a microprocessor and thereby
reduce the number of crystals required in the system design. The driver has an
internal resistor in series with the output whch can be combined with an external
capacitor to form a low pass filter to reduce radiated noise on the PCB. This output
also functions as the output for the counter test modes.
This pin indicates when the internal latches may have lost memory due to a power
glitch.
Dual function pin; 1) Carrier detect output (open collector with external 100 k
pull–up resistor. 2) Hardware interrupt input which can be used to “wake–up” from
Inactive Mode.
Low battery detect output (open collector with external pull–up resistor).
Data amplifier output (open collector with internal 100 k pull–up resistor).
Speaker amplifier output.
Speaker amplifier input (ac coupled).
Expander output.
V CC supply for audio section.
Data amplifier input (ac coupled).
Pre–amplifier output for connection of pre–amplifier feedback resistor.
R x audio input to pre–amplifier (ac coupled).
Audio output from FM detector.
Receive signal strength indicator filter capacitor.
Note used.
A quad coil or ceramic discriminator are connected to this pin.
V CC supply for RF receiver section.
IF amplifier/limiter capacitor pins.
