From 25 to 70 C, the edge of the clock CKDATA has a shift of 1 phase compared to CKREF.
Effective bits are obtained from a Fast Fourier Transform (FFT) treatment taking 8000 acquisition points per equivalent fundamental
period. The calculation takes into account all harmonics and noise up to half clock frequency (NYQUIST frequency).
Conversion-to-noise ratio: S/N = EB
Output data acquisition: the output data is available after the maximum sampling delay time t
capacitive load.
Pulse relative to the blank level.
The I
400 kbit/s (400 kHz).
PLL long-term time jitter is measured at the end of the video line, where it is at its maximum.
