[Note to the characteristics]
1. If measured in the burst period of a blue line.
2. Pin 16 is AC - coupled. Defined the impedance over f = 4MHz.
3. Measure except during the vertical blanking and burst gate pulse.
An use of an active probe is advised for low capacitive loading.
4. Defined as V
LIN
= b / a ; see fig.6
5. Measure the difference voltage between the blanking(V1) and the black(V2) level .
Defined as
V
RB
(
V
BB
) = V2-V1 ; see fig.7
6. Defined as the time from rising edge detection of PAL burst gate pulse at pin15.(internal)
7. Defined as the time from falling edge detection of PAL burst gate pulse at pin15.(internal)
8. The reference signal should be stable during the vertical blanking.
9. The external supply voltage at pin1 should be exceed 0.5V.
10. Defined as the ratio between V
K
(i.e. the peak to peak value of the burst period
of a blue line) when LOW (0 .2 V) at pin5, and 167 mVp-p the peak to peak value
of the burst period of a blue line.
I / K = 20 * log10 (Vk / 167 mVp-p) (dB)
