TEST CONDITION (VCC = 9V, Ta = 25Â±3Â°C)

MEASUREMENT METHOD

(1) Change the voltage of external input signal at picture period at pin 39.

(2) Consider the output change at pin 21 as 100%.

Measure the output signal amplitude at pin 21 when the output signal is 10%

(Vdi1) and when the output signal is 90% (Vdi2).

Vdi45 = Vdi2âVdi1

(1) Apply a rainbow color bar signal to pin 39.

(2) Measure the RGB output signal as F1 and F3 at pin 19, 20 and 21 when the

input signal level is 100mVp-p and 300mVp-p.

A = F1 / F3

Control Range

58 VCXO Frequency

Control Sensitivity

Apply the burst signal (50mVp-p) to pin 39.

Decrease the input level by using ATT.

Measure the input burst signal when color killer on.

(1) Measure the DC voltage at pin 11. (V11)

(2) Measure the frequency change at pin 12 when the voltage of pin 11 is change

from V11â0.5V to V11+0.5V.

(1) Same as Note 57 (1)

(2) Same as Note 57 (2)

(3) Measure the sensitivity against 1mV at pin 11.
