(2) Clock synchronization
The triangular wave can be synchronized by inputting to
the CLK pin (pin17) a pulse wave equal to 0–Pre.V
p). The following precautions should be kept in mind:
S The amplitude of the triangular wave decreases as the
clock frequency rises.
(3) Using the ESP pin
Optical disc ICs
1. To operate the PWM driver at 176.4kHz
2. To operate the PWM driver at 88.2kHz

(Vp-
S The PWM driver is a voltage feedback driver, which
should preclude any problems unless the setting is such
that the triangular wave has an extremely small ampli-
tude.
S As mentioned above, a capacitor and resistor are also
required during clock synchronization.
