EXPLANATION
tSRD
Delay between sample reset (SR) rising edge and
actual sampling instant (ns)
6
This is the fixed internal delay in the chip. The reset
value of the CCD waveform should be stable until
the end of this period.
tSVD
Delay between sample video (SV) rising edge and
actual instant of video signal sampling (ns)
6
This is the fixed internal delay in the chip. The video
signal value of the CCD waveform should be stable
until the end of this period.
tADC_SV
Time between ADCCLK falling edge and SV falling
edge
3
The timing margin required to ensure the ADCCLK
positive half cycle is in between two SV pulses
