Product specification

Baseband delay line

TDA4665

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

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