3. Supposing that the measured value is treated as amplitude V
OR1
(V
OG1
or V
OB1
) when SG1 is input, as V
OR8
(V

) when
SG2 is input, or as V
OR9
(V

) when SG3 is input,
frequency characteristics F
C1
and F
C1'
are calculated as follows:
4. Frequency relative band widths
F
C1

are equal to the
difference in F

C.T.1 Crosstalk1 (f=50MHz)
C.T.1' Crosstalk1 (f=130MHz)
1. Measuring conditions are as given in Supplementary Table.
2. Input SG2 (or SG3) to pin 11 (R-ch) only, and then measure the
waveform amplitude output at T.P21 (25 or 29). The measured
value is called V
OR
, V
OG
and or V
OB
respectively.
3. Crosstalk C.T. 1 is calculated by the equation below:
C.T.2 Crosstalk2 (f=50MHz)
C.T.2' Crosstalk2 (f=130MHz)
1. Change the input pin from pin 11 (R-ch) to pin 7 (G-ch), and
measure the output in the same way as in C.T.1, C.T.1'.
2. Crosstalk C.T. 2 is calculated by the equation below:
C.T.3 Crosstalk3 (f=50MHz)
C.T.3' Crosstalk3 (f=130MHz)
1. Change the input pin from pin 11 (R-ch) to pin 3 (B-ch), and
measure the output in the same way as in C.T.1, C.T.1'.
2. Crosstalk C.T. 3 is calculated by the equation below:
Tr Pulse characteristics1
Tf Pulse characteristics2
1. Measuring conditions are as given in Supplementary Table.
2. Measure the time needed for the input pulse to rise from 10% to
90% (Tr1) and to fall from 90% to 10% (Tf1) with an active prove.
3. Measure the time needed for the output pulse to rise from 10%
to 90% (Tr2) and to fall from 90% to 10% (Tf2) with an active
prove.
4. Pulse characteristics Tr and Tf are calculated by the equation
below:
V14th Clamp pulse threshold voltage
1. Measuring conditions are as given in Supplementary Table.
2. Turn down the SG5 input level gradually, monitoring the output
(about 2.0 VDC). Measure the SG5 input level when the output
reaches 0V.
W14 Clamp pulse minimum width
Under the same conditions as given in V14th, reduce the SG5 pulse
width gradually, monitoring the output. Measure the SG5 pulse
width when the output reaches 0V.

1. Measuring conditions are as given in Supplementary Table.
2. Measure the pedestal voltage at room temperature.
The measured value is called P

.
3. Measure the pedestal voltage at temperatures of -20
°
C and
85

V1th BLK input threshold voltage
1. Measuring conditions are as given in Supplementary Table.
2. Make sure that signals are not being output synchronously with
SG7 (blanking period).
3. Reduce the SG7 input level gradually, monitoring output.
Measure the SG7 level when the blanking period disappears.
The measured value is called V1th.
