Description
Connect to the 7.2 MHz crystal oscillator.
Chip enable terminal. Connect to the PLL terminal of microprocessor.
Serial clock input terminal. Connect to the CLOCK terminal of microprocessor.
Serial data input terminal. Connect to the DATA terminal of microprocessor.
Not used.
AUTO/MONO selection output terminal. "L" when AUTO.
FM band control output terminal. "L" when FM.
AM band control output terminal. "L" when AM.
AM local oscillator input terminal.
FM local oscillator terminal.
Power supply terminal for back-up.
Power supply terminal.
Charge pump output of the phase detector which constitutes the PLL. High level is output when the
divided local oscillator frequency is high than the reference frequency.
In the opposite case, low level is output. Floating occurs when the frequencies matched.
The output is applied to the variable capacitor diode in the local oscillator through the low pass
filters.
Ground terminal.
