terminals.

The

reception

frequency

data

is

delivered

from

the

DATA

terminal

(pin

22).

[Example]

AM

1000

kHz

[Example]

FM

100

MHz

Phase

comparator

output

terminal.

When

the

phase

of

the

frequency-divided

output

of

the

programmable

counter

lags

behind

the

reference

frequency,

the

output

at

the

phase

comparator

output

terminal

goes

“L”

for

the

period

corresponding

to

the

phase

difference.

When

the

counter

output

leads,

the

comparator

output

goes

‘‘H”

for

the

period

corresponding

to

the

phase

difference.

Muting

output

terminal.

The

muting

output

is

delivered

from

the

MUTE

terminal

at

the

time

of

key

operation

and

other

cases.

FM

programmable

counter

input

terminal.

The

FM

local

oscillation

signal

which

is

divided

into

1/30

or

1/32

by

the

prescaler

(IC6

RVITD6104P)

is

inputted

to

this

terminal.

[Example]

FM

This

is

the

terminal

to

deliver

the

frequency

dividing

ratio

change

over

output

signal

to

the

pre-scaler

(1C6

RVITD6104P).

AM

programmable

counter

input

terminal.

The

AM

local

oscillation

signal

is

directly

applied

from

8

of

IC301

(PVIUPC1215VE)

to

the

AM

IN

terminal

in

the

AM

mode.

Inhibit

input

terminal.

When

the

power

is

turned

on,

the

voltage

rising

time

at

the

INH

terminal

(pin

40)

is

delayed

for

a

certain

time

[the

time

constant

of

R90

(100

and

C94

The

band

is

read

during

this
