9 / 15 page  LA75503V No.6804-9/15 Continued from preceding page. Pin No. Pin name Pin function Equivalent circuit 11 12 VCO COIL This is the VCO tank circuit for the PLL detector. Use a tuning capacitance of 24pF. Use L and C specifications that are accurate to ±2%. Also, design the L and C values so that the voltage of pin 10 is 3.6V when PLL is locked while using the IF center frequency. 13 14 SYSTEM SW [A] SYSTEM SW [B] This is the system switch pin. The transistor turns ON when the pin voltage from the circuit becomes approx. 1.4V. 15 REF OSC This pin can be used both as the crystal resonator pin and IF switch. The 38MHz mode is selected by inserting 220k Ω between pin 15 and GND, the 38.9MHz mode by leaving the pin open, and the 39.5MHz mode by inserting 220k Ω between pin 15 and VCC. 4MHz input is possible from this pin. In the case of 4MHz external input, input 86dB µ Continued on next page. |
