Notes
1. For SECAM the signal must be blanked line-sequentially. The blanking level must be equal to the non-colour signal.
For SECAM, PAL and NTSC the input signal must be equal to the non-colour signal during the internal clamping of
TDA4665 (3 to 1
µs
before the leading edge of the top pulse of V
5
).
2. Noise voltage at f = 10 kHz to 1 MHz; R

Ω.
3. The leading edge of the burst-key pulse or top pulse is used for timing.
