All maximum current values are guaranteed by characterization to assist in power supply design.
2
Typical current consumption values are recorded with nominal voltage supply levels, SMPTE bar video pattern, and at room temperature.
3
Maximum current consumption values are recorded with maximum rated voltage supply levels, MoireX video pattern, and at maximum rated temperature.
4
Termination power supply includes TVDD current consumed off chip.
5
Power-down mode entered by setting Bit POWER_DOWN high.
