Notes:
5. The above data is typical at 25^oC with the following supply voltages: DVDD=3.6V, AVDD=5.0V and
VDD=5.0V
6. Current is mesured in normal circuit configuration with output loads connected; device operating in mode 17
with P-OUT at 2X.
7. Actual current will depend on many factors, including operating mode, image content, output clock
selections, etc. This table is intended as a general guide only.
