2) Output signal waveforms of LCD segment
The illumination or nonillumination of segments (LCD1~23) on the LCD is determined by the
combination
of
the
segment
drive
signal
and
the
common
drive
signals
(COM1
and
2)
from
IC401.
(See Fig. 3.)
The illumination or nonillumination of segments other than LCD1~23 (FM, Tape, HS, DO) is deter-
mined by the combination of the 80Hz signal made by the oscillation circuits in Q403 and Q404
and the segment drive signal made in IC 402.

3) Function of terminal (PLL controller 1C401)
Segment signal output terminal for display. (Refer to Fig. 1.)
Common signal output terminal connected to LCD. Output is delivered in
3 values of ground, 1/2Vop and Vop (at 5ms intervats) in a period of 50Hz.
The segment turns ON when the difference in voltage is + Vop between
these terminals and LCD1~LCD23.
Power supply terminal of device. Voltage of 5V+10% is supplied during
operation of device: To hold the internal data memory (RAM), the voitage
can be decreased to 2.5V.
Note: Pins 7 and 33 are connected inside the chip. it is unnecessary to
supply voltage to the pins.
Input is local oscillator output (VCO) in a range of 10~130MHz (0.3Vp-p,
min.).
There are 1/2 fixed frequency division prescaler and 2-step (1/32, 1/33)
prescaler internally. Therefore, when deciding the frequency dividing
value of programmable divider, it must be decided from the frequency
‘ obtained by halving the local oscillator output (VCO).
Input is local oscillator output (VCO) in a range of 0.5~20MHz (0.1Vp-p,
min.).
When the mode is shifted to FM, the AM terminal voltage automatically
becomes the supply voltage of device.
Ground terminal.
When the divided oscillator frequency is higher than the standard frequen-
cy, H-level output is delivered from these terminals.
When it is lower, L-level (0V) output is delivered. When they coincide, it
results in floating.
Device selection signal input terminal. The signal level should be high
when the device is operated, and low when not operated.
With this terminal shifted to low level, LCD (liquid crystal display) turns off
and the memory is held.
Not used in this unit.
Connecting terminal for crystal oscillator. The crystal connected is
4.5MHz.
Inputs high signal when broadcast is received during auto tuning in the
radio mode and low signal at all other times.
Outputs high signal when ambience switch is pressed and turns on Q18.
