Pin Function
Internal Circuit
This is the VCO tank circuit for the PLL detector.
Use a tuning capacitance of 24 pF.
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 3.6 V when PLL is locked while
using the IF center frequency.

12
VCO COIL
This is the system switch pin.
The transistor turns ON when the pin voltage from
the circuit becomes approx. 1.4 V.
13
14
SYSTEM SW
This pin can be used both as the crystal resonator
pin and IF switch.
The 38-MHz mode is selected by inserting 220 k
between pin 15 and GND, the 38.9 MHz mode by
leaving the pin open, and the 39.5-MHz mode by
inserting 220 k
between pin 15 and V
CC
.
4-MHz input is possible from this pin.
In the case of 4-MHz external input, input 86 dBμ
or more.
