Quartz PLL Motor Control
QUARTZ PLL MOTOR CONTROL
The TC9142P is a c2-rsos LSI developed for con-
trolling the motor of a quartz-lock D.D. record
player. Since an 8-bit D/A converter system
has been employed for each of the speed control
system (AFC) and the phase control system (APC),
a wide reduction of external parts can be made
in comparison with conventional capacitor-type
S/H systems, thus having realized adjustment
free operation.
Has built-in AFC and APC, for each of which
8-bit D/A converter system has been employed.
Speed-changeover positions are available at
33 1/3 and Ci-rpm.
Crystal can he used up to 12 MHz, and crystal
reference dividing frequency is selectable
from three positions of 1/4, 1/32 and 1/128

EXPLANATION OF OPERATION
Crystal oscillation terminals (XT, YT )
. The crystal oscillator is used by connecting as shown below.
, , a C OF lonvsopF is appropriate.
TRIMMER UI, Cl, L
. Crystal oscillation frequency is calculated by the following equation
according to number of FC pulses of a motor to be used.
fx = 3/4 FG'x 128x 20:XN = 5/9 FG'X 128x 27x N = 1920 FC'. N (Hz)
(Note) 3/4 FG' l FGIN frequency at 45rpm.
5/9 FG' l FGIN frequency at 33 1/3rpm.
Further, fx: Crystal oscillation frequency, FC'.. No. of FG pulses gen-
erated per revolution of motor.
N .' Ratio of frequency division of the crystal reference frequency
divider. (Refer to Item (10).)
. Maximum operating frequency is above 12MHz and crystals up to 12MHz
can be used.
Reference frequency input/output terminals (CPOUT, CPIN)
. Divided output IJ-. from the crystal reference frequency divider is
available at CPOUT: which is normally connected to CPIN.
. When an external oscillator (CR oscillator, etc.) is connected to
CPIN, motor speed can be finally adjusted.

(3) Strobe reference frequency output terminal (STROBE)
. . . 1
. This is the reference output terminal for strobe and 32 y: 20 or 27 xl
of crystal oscillation frequency is available at this terminal.
. Duty is 1/8 and suited to a single stripe strobe.
(4) FG pulse input terminal (FGIN)
. This is the input terminal of FC pulse that shows the motor speed.
This FG pulse becomes comparison frequency.
. This terminal has built-in Amplifier and Schmitt circuit.
FO pulses are applied through capacitor coupling and small amplitude
is enough for proper operation.
(5) Speed switching terminal (33/45)
. This terminal is for switching the motor speed 33 1/3 and 45rpm,
with a pull-up resistor and chattering preventive circuit.

(6) APC, AFC output terminal (APC, AFC)
AFC (speed control output) is a F-V converter for FG frequency,
and is consisting of a 8bit D/A converter.
APC (phase control output) is a phase comparator (4-N converter)
that compares phase difference é between 1/2 FG and reference
frequency FS' , and is also consisting of a 8bit D/A converter.
Both APC and AFC perform the following 3 operations according to
FGIN frequency.
