Test Conditions and Measuring Method (VCC = 9 V, Ta = 25 ± 3°C, unless otherwise specified)
HB03
HD output pulse width
(free-run)
c
b
(1)
BUS control data preset.
(2)
When horizontal oscillation frequency is 28.125 kHz (00), measure the output pulse width TH00 of pin 16
(HD1-OUT) wave form.
(3)
When horizontal oscillation frequency is 31.5 kHz (01), 33.75 kHz (10), 45 kHz (11), measure the output
pulse width TH01, TH02, TH03 as well.
HB04
Horizontal free-run frequency
OPEN
b
(1)
BUS control data preset.
(2)
SW7 open. When horizontal oscillation frequency is 28.125 kHz (00), measure the oscillation frequency F00
of pin 16 (HD1-OUT) wave form.
(3)
When horizontal oscillation frequency is 31.5 kHz (01), 33.75 kHz (10), 45 kHz (11), measure the oscillation
frequency F01, F10, F11 as well.
(4)
When horizontal oscillation frequency is 31.5 kHz (01) and vertical free-run frequency is (001), measure the
oscillation frequency F50 of pin 16 wave form.
HB05
Horizontal oscillation control sensitivity
OPEN
b
(1)
BUS control data preset.
(2)
SW7 open.
(3)
Connect external voltage with pin 7 . Horizontal oscillation frequency is 28.125 kHz (00). Supply V7 (about
6.3 V)
+ 0.05 V or V7 0.05 V to pin 7, then measure the frequency FA, FB of pin 16 (HD1-OUT) wave form.
Calculate frequency changing ratio (BH00). BH00
= (FB FA)/0.1
(4)
When horizontal oscillation frequency is 31.5 kHz (01), 33.75 kHz (10), 45 kHz (11), calculate BH01, BH10,
BH11 as wall.
