Figure 18. Timing constraints for row readout initialization (blanking time)
Figure 18. and Table 9. illustrate the timing constraints of the
row initialization/ blanking sequence.
• The EOS_X pulse flags the end of the scanning of previous
line, and should be considered as a diagnostic means only.
The blanking sequence could start earlier or later.

Ta
Min 0
Delay between falling edge of CLK_Y* and SHY or SIN
Tc
Min 25 ns
CLK_YR & CLK_YL high time
Ts
Typ. 3 us
On-time of SIN (offset calibration pulse)
Delay between selection of new row and end of column amplifier calibration
Tw
Typ. 200 ns
Delay between end SIN and pixel reset
Tr
Typ. 1 us
On-time of reset pulse
Th
Typ 1 us
Th + Tr = Delay between pixel reset and column sample & hold
To
Typ 100 ns
Delay between SHY and L/R\
Overlap of L/R\ over 2nd reset pulse
Tm
Min 25 ns
On-time of one of the SYNC pulses. SYNC==low may only occur when the
associated CLOCK is high.
Tn
Min. 200 ns
Delay between SHY and start row readout
