Data input/output pin of electronic volume control For details of data output, see Appendix. Charge pump output pin of phase detector built into a PLL. If a divided oscillator frequency is higher than the reference frequency, the output of this pin goes high. If the divided oscillator frequency is lower, the output goes low. If the divided oscillator frequency agrees with the reference frequency, the output enters the floating state. Power-supply pin of the device This pin supplies a voltage of 5 V ±10 % while the device is operating. The rise time (0 to 4.5 V) of VDD must not exceed 500 ms. If the rise time is significantly long or if the voltage falls below the operating voltage but is between 0 V and 3.5 V, the state of an initial setting diode switch may be read incorrectly. Input pin of the local oscillator output (VCO) in the AM (MW, LW) band When tuned to broadcasts in the MW or LW band, this pin becomes active. Otherwise, the pin is internally pulled down. To protect the built-in AC amplifier, block the flow of direct current with a capacitor, then input the frequency. Input pin of the local oscillator output (VCO) in the FM band When tuned to broadcasts in the FM band, this pin becomes active. Otherwise, the pin is internally pulled down. Because an AC amplifier is incorporated, block the flow of direct current with a capacitor, then input the frequency. Input pin of the device selection signal Always pull up the pin. Serial clock output pin for controlling the LCD controller/driver ( µPD7225) Serial data output pin for controlling the LCD controller/driver ( µPD7225) Input pin of the door switch See Chapter 3 for details.
