Test Method
A (1) Set SA 00H data to C0H.
(2) Input 15.734-kHz composite video signal to D-SYNC1/Y3 IN.
(3) Measure #17 (HD OUT) and #30. Measure phase difference HDS0 and pulse width HDW0.
(4) Set SA 00H data to C2H. Input signal c (T = 31.75 µs, t = 2.35 µs) and measure phase difference HDS1 and
pulse width HDW1.
(5) Set SA 00H data to C4H. Input signal c (T = 29.63 µs, t = 2 µs) to D-SYNC1/Y3 IN and measure phase
difference HDS2 and pulse width HDW2.
(6) Set SA 00H data to C6H. Input signal c (T = 24.1 µs, t = 1.65 µs) to D-SYNC1/Y3 IN and measure phase
difference HDS3 and pulse width HDW3.
(7) Set SA 00H data to CCH. Input signal c (T = 14.815 µs, t = 1 µs) to D-SYNC1/Y3 IN and measure phase
difference HDS4 and pulse width HDW4.
(8) Set SA 00H data to FEH. Input signal c (T = 31.75 µs, t = 2.35 µs, amplitude = 1.5 V) to D-SYNC1/Y3 IN and
measure phase difference HDS5 and pulse width HDW5.
