FM:
PLL filter formed with pins 9 to 12
(Pins 10 and 11 to be left OPEN)
AM:
PLL filter formed with pins 10 and 11. In this case,
the low pass filter is formed with the internal
impedance (100k
Ω) and external capacity.
Simultaneous use of AM and FM filters (pins 9 to
12) is possible through mode changeover. In this
case, internal impedance (100k
Ω) is short-circuited.

AM/FM SD
ON=High
OFF=Low
Pin 14 output is output from DO (for SD information
output).
VCO monitor (at IN3-5 D6=H)
Saw-tooth wave of MPX-VCO frequency is output,
which is monitored for VCO adjustment
(Adjust with IN3-5 D0-5.)
15
Separation adjustment
pin
The input level of sub-decoder is varied through
BIT control.
(The output level of MONO and MAIN remains
unchanged.)
