EXPLANATION HOW THE LS! QUARTZ
PLL MOTOR CONTROL OPERATES
© LSI motor control ... TC9142P.
{33 r.p.m, is set as the standard speed)
© Due to C-MOS construction, handle this IC with ex-
treme care.
O Vin (min) ..0.7 x Veo =3.6V
© Vy (max.)..,0.3 x Vee = 1.5V
© In terminals 4, 5, 10, and 11, pull-up resistors are
built in,
Terminal 1 : GND
Terminal 2 : OSC OUT (7.68 MHz)
O13 us”
Terminal 3 :
OSC IN (7.68 MHz) _
Terminal 4 + Internal frequency divider ratio switch
and5 Terminals 4 and 5 determine the frequency
dividing ratio of the internal frequency
divider,
Terminal 6 : FG input
T= 1.8 ms (33 rpm)
= 7.33 ms (45 rpm)

AFC output
Speed (frequency) control system output of
the motor
Same in either 33 rpm or 45 rpm
33/45 rpm switch input
L ... 33-1/3 rpm
H,,, 45 rpm
: PLAY/STOP input
L ... PLAY
H ... STOP
Lock detector output

Reference frequency input (CR IN)
Connected to terminal 15
Reference frequency output {CP OUT}
In accordance with the ratio set by terminals
4 and 5, the divided frequency output is
obtained, . a
