Notes to the characteristics
1. If measured in the burst-period of a blue line.
2. The video input is AC-coupled.
3. During scan.
4. Measured as 100% x (IV
5. Converted to input frequency error.
6. Defined as the ratio between the peak-to-peak value of the B Y component of the demodulated 100/75 colour bar
7. The reference should be stable during frame blanking.
8. The SECAM enable and disable timing should preferably be at the end of the frame blanking.
9. The externally supplied voltage should exceed 0.5 V.
