Burst width for PAL and NTSC 2.25
μ
s, ratio burst chrominance amplitude 1/2.2.
2.
At nominal phase of hue control.
3.
V (p-p) of signal divided by 6 times effective noise voltage.
4.
At NTSC 3.58 35 mV (p-p).
5.
H/2 blanking alternately every second line.
6.
These pins are leakage current sensitive. Pin 4 for (B-Y) Channel, pin 10 for (R-Y) Channel.
7.
Within 2 dB output voltage deviation.
8.
This pin is leakage current sensitive.
9.
IC only.
10. Depends also on network on pin 17.
11. Pin 23 for PAL, pin 22 for SECAM, pin 21 for NTSC 3.58 MHz, pin 20 for NTSC 4.43 MHz.
Threshold levels are dependent on supply.
12. The field interval of the sandcastle has to be adapted to the ICs TDA2579B and TDA4690.
The thresholds are independent of supply voltage.
13. System scanning sequence: PAL, SECAM, NTSC 3.5, NTSC 4.4.
