7 / 13 page Continued from preceding page. No. 4787-7/13 LA1836, 1836M Pin No. Function Voltage Internal equivalent circuit Remarks 23 24 25 26 27 28 29 30 MPX VCO AM/FM demodulator output AM low cut AM AGC AM RF input AFC OSC Oscillator buffer output, FM SD sensitivity adjustment 3.5 V (FM) 0 V (AM) 2.9 V (FM) 3.0 V (AM) 2.9 V (FM) 3.0 V (AM) 0 V (FM) 0.5 V (AM) VREG VREG VREG 1.6 V (FM) 1.3 V (AM) Recommended ceramic resonator: CSB456F15 (Murata) Output impedance: 1.5 k Ω (FM), 10 kΩ (AM) The separation can be adjusted with the external capacitor connected between this pin and ground. The AF demodulation frequency low area frequency characteristics can be adjusted with the external capacitor connected between this pin and ground. The AM detector output can be attenuated by connecting a resistor in series with this capacitor. Internal load resistance: R = 6.7 k Ω This pin must be used at the same potential as pin 4. The FM-SD bandwidth can be adjusted with the external resistor connected between this pin and pin 4. The oscillator coil is connected between this pin and pin 4. The FM SD sensitivity can be adjusted with the external resistor connected between this pin and ground. Output impedance ro = 200 Ω |
