Pin Function
This is the VCO tank circuit for the PLL detector.
Use a tuning capacitance of 24 pF.
11
Use L and C specifications that are accurate to
VCO COIL
±2%. Also, design the L and C values so that the
12
voltage of pin 10 is 3.6 V when PLL is locked while
using the IF center frequency.
Internal Circuit
13
This is the system switch pin.
14
SYSTEM SW
The transistor turns ON when the pin voltage from
the circuit becomes approx. 1.4 V.
This pin can be used both as the crystal resonator
pin and IF switch.
The 38-MHz mode is selected by inserting 220 kΩ
between pin 15 and GND, the 38.9 MHz mode by
leaving the pin open, and the 39.5-MHz mode by
15
REF OSC
inserting 220 kΩ between pin 15 and VCC.
4-MHz input is possible from this pin.
In the case of 4-MHz external input, input 86 dBµ
or more.
