Ts
Typ. 3 us
On-time of SIN (offset calibration pulse)
Delay between selection of new row and end of column amplifier calibration

Delay between end SIN and pixel reset
Tr
Typ. 1 us
On-time of reset pulse

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
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.
