NOTES
1The typical pattern contains a gray scale area, Output Drive = High.
2The worst-case pattern contains a black and white checkerboard pattern, Output Drive = High.
3The setup and hold times with respect to the DATACK rising edge are the same as the falling edge.
41 Pixel/clock mode, DATACK and
DATACK Load = 10 pF, Data Load = 5 pF.
CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection. Although
the AD9887 features proprietary ESD protection circuitry, permanent damage may occur on
devices subjected to high-energy electrostatic discharges. Therefore, proper ESD precautions are
recommended to avoid performance degradation or loss of functionality.
WARNING!
