The programmable counters for FM and AM (NN/W) are In different circuit
configuration.
I) FM Programmable Counter
The FM programmable countef is of swallow count type in combination
with TD6104P. As a result, reference frequency 25 kHz is obtained and
performance ls Improved.
The following diagram shows the connection with prescaler TD6104P.
In this case, the transmission
delay time of PSC output for
controlling TD6104P is limited.
Therefore, wiring for this PSC
output should be as short as
possible. PSC transmission

The phase comparator ls a unit that compares phases of reference
frequency and programmable counter output and controls VCO through the low

. Two tri-state buffers DO-l and D0-2 are transmitted para11ely from one
phase comparator. Becuase of this, two sets of low-pass filter can be
used without necessity for switching them.

1. DETERMINATION OF OSCl AND OSC2 OSCILLATION FREQUENCY
0SCI and OSC2 are C and R connecting terminals of a single terminal
type oscillator. Sean speed at time of manual fast forward and auto
search is decided by this frequency.
0SCI is for FM and OSC2 ls for AM and oscillation frequency can be
set independently. Further, OSCI oscillation frequency also seves for
deciding manual fast forward pushing time, muting signal transmission
time and store state automatic releasing time.
Both 0301 and osc2 stop oscillation unless it ls required.
Oscillation Frequency fosca-- 0.7 CXRX (Hz) (Note 2)

2. DESIGNATION CP DESTINATION BY JAPAN, U.S.A AND EUROPE
Regional designation by Japan, U.S.A and Europe ls made by El and E2 terminals.

1 0 Europe
0 1 bill 9 kHz separation
U.S.A. V
1 1 Mil 10 kHz separation
. For U.S.A region designation, AM(MW) band 9 kHz/lO kHz separation can be
selected.
. when the IMrtermtnal is placed at "L" level, E1 and E2 Inputs inhibit
read operation and keep the previous state.
3. SELECTION OF RECEIVING BAND
C. The receiving bands are selected by the FM, Mil and IM terminal Inputs.
3 bands of FM/MW/LW are selected for European region designation and 2 bands
of FN/AN (W) for Japan and U.S.A designation.
. FM, WI and Lil inputs are of mutual reset type and are "H" level active.
. I/0 type with a built-in bipolar transistor driver, and the band display by.
LED is possible.
. Has the Internal latch circuit and able to correspond to either the push key
or lock switch. The key connection ls shown tn the following diagram.
However, when the lock switch is used, different band memory channels under
the random memory system cannot be read.
. Input by multiple pushing the key is not accepted and muting output becomes
"H" level.
. No LTI input ls accepted in Japan and U.S.A designation.

Ih order to prevent generation of abnormal sound at time of key operation,
muting signal ls transmitted from the MUTE terminal at .the timings shown
in the following diagrams.
Muting output time at time of restoration from the inhibit state or band
switching Is extended to about 2 times of that in normal cases.
(This is also, true when a band is changed according to the memory read
In the random memory system.)
. When the multiple band Input keys are pushed' or during the fast forward-
! ing or auto search tuning, muting output ls kept at "H" level.,
. The receiving channel (division of the programmable counter) changes
1 12 mS later after muting signal ls transmitted. This will provide a
margin to muting application time.

A11 transistor for the drivers are turned OFF and all other outputs
are held at "L" level.
As the result of above operations, current consumption at the inhibit state
is reduced extremely. Therefore, the back up by means of battery pr

---- PROGRAMMABLE COUNTER INHIBIT STATE
. When the TNT, terminal ls set at "L" level, a series of operations Is
executed ln the Inside of LSI for shifting to the Inhibit state.
It is necessary to apply normal voltage (4. 5'h5. 5V) to VDD terminal
during this series of operations. Thereafter, hm can be reduced to
backup voltage (2V).

. As mentioned above, E1 and E2 terminals Inhibit read when the -ITi, terminal
is at "L" level. However, data read is immediately sta-r-ted when the INH
terminal Is placed at "H" level. Therefore, rise of INH Input should be
delayed more than hm.
