MEASUREMENT METHOD
1) When 0V (DC) is input from an external power supply to pin 7, when 7.5
V is input to pin 7, and when no external voltage is applied to pin 7,
measure the picture period amplitude of pin 13.

(VOSD1R, VOSD2R, VOSD3R)
2) As in step 1) above, input to pin 8 and measure pin 14, then input to pin 9
and measure pin 15.
(VOSD1G, VOSD2G, VOSD3G)
(VOSD1B, VOSD2B, VOSD3B)
1) Input signal 1 (f = 100 kHz, picture period amplitude = 0.2 Vp-p) to pin 7.

2) Apply an external power supply to pin 10. Gradually increase the voltage
from 0 V.
3) When signal 1 is output to pin 13, measure the pin 10 voltage.
1) Apply 2.5 V from an external power supply to pins 7, 8, and 9.
2) Input signal 4 (signal amplitude = 4.5 Vp-p) to pin 10.
3) Measure the switching transfer characteristics of pins 13, 14, and 15

according to diagram T-2.
4) Using the data obtained from the above measurements, calculate the
maximum axis difference between the rising and falling edge of the
transfer delay time.
1) Set the bus control data to read mode and reset.
2) Set to read mode again.
3) Check that the read mode parameter (RGB-OUT) is 0 (error).

using an external power supply.
5) Set to read mode again.
6) Check that the read mode parameter (RGB-OUT) is 1 (OK).
