Main

features

(IC

HA1137W)

1.

This

IC

includes

all

functions

required

in

FM

iF

stage.

2.

As

indicated

above,

this

IC

has

functions

of

Muting

circuit

which

operates

below

a

certain

input

signal

level.

And

also

the

IC

includes

new

muting

circuit,

namely

it

has

0

volt

switch

which

operates

the

mu-

.

ting

circuit

when

the

difference

(absolute

value)

of

detector

output

voltage

between

Tuning-ON

and

Detuning

exceeds

a

certain

voltage,

utilizing

S-curve

characteristics

of

FM

detector.

By

this

advantage,

it

is

possible

to

eliminate

or

avoid

“Pop

noise”

caused

by

variation

of

the

DC

voltage

at

tuning-OFF.

3.

The

IC

makes

it

possible

to

produce

high-quality

tuner

having

better

selectivity

and

sensitivity

by

connecting

6-element

filters

between

Front-end

and

the

IC,

as

it

has

higher

gain

and

better

suppression

ratio

in

amplitude

modulation.

Main

features

of

PLL

(IC

HA1196)

In

the

multiplex

demodulation

circuit,

because

of

sub-

carrier

wave

(38kHz)

being

required

for

demodulation,

the

pilot

signal

(19kHz)

sent

from

FM

stereo

broadcast-

ing

station

is

being

made

while

doubling.

It

is

necessary

for

this

sub-carrier

wave

that

its

phase

confirms

to

that

of

pilot

signal

correctly,

and

if

there

is

any

phase

difference

between

them,

FM

stereo

separa-

tion

becomes

poor.

In

the

conventional

products,

LC

resonance

circuit

has

been

used

so

far

for

the

circuit

of

this

section,

on

the

other

hand,

in

model

7070,

IC

in

PLL

is

used,

which

prevents

FM

stereo

separation

from

becoming

poor

due

to

deviation

in

resonance

frequency

or

phase

to

tempa-

rature

change

and,

in

result,

ensures

stereo

separation

of

more

than

50dB

at

1kHz.

Advantages

1)

Selectivity

is

superior.

2)

Phase

characteristics

is

good.

3)

It

is

virtually

not

affected

by

temperature.

4)

No

secular

change

occurs.
