SYNC SIGNAL PROCESSOR

are input.

3) Polarity detection and non-input detection (pins

and

)

External capacitance is required as a ﬁlter pin to detect polarity

and non-input. As the value is larger, the ripple is smaller and

less malfunction occurs. However, the response speed for

detection is lower. A sufﬁcient external capacitance is 0.05 µF

with input of 15 kHz and 10 uF with input of 60 kHz. However,

check the frequency of the input signal in use and the ﬁlter pin

waveform with the duty ratio conditions, and then check that the

value is 3.1V or more (2.8V in capability) with positive polarity

input and 1.9V or less (2.2V in capability) with negative polarity

input.

VD portion

1) Clamp pulse width

CLAMP TIMING (Pin

)

The clamp pulse width is determined by the external resistance

and the capacitance. As the resistance value and capacitance

value are larger, the clamp pulse width is wider.

Output at pin

when pin

is "L"

Output at pin 15 when pin

is "H" or OPEN

The time constant is determined by the current ﬂowing out of pin

and the capacitance value of the timing pin. The ﬂow current

at pin

is determined by the pin voltage and external resistance

value. When the external resistance is 4.3 Ω (that is 700 uA) and

VD portion

the external capacitance is 220 pF, the pulse width is 0.4 usec.

2) Clamp pulse position

CLAMP SW (pin

)

Output at pin

when pin

is "L"

When pin

is "M" or "L", ﬁxing a higher-priority signal to the

trailing edge results in occurrence of a clamp pulse. When pin 3

is 'H", and only GREEN is input, clamp pulse occurs at the

trailing edge. A clamp pulse also occurs at the leading edge
