11.0 Power Consumption
The AL128 works at +5V or +3.3V, but the support of input resolution and refresh rate may be
limited at the lower power. For full functionality of the AL128, the power needs to be more than
+3.8V. At +3.3V, the AL128 can only support 640x480 resolution up to 85Hz and 800x600
resolution up to 60Hz. The following table shows the current consumption of the AL128 at different
supply voltages.

Please be reminded that when lower power supply is used, the pull-down resistance to the RSET pin
has to be adjusted to compensate (in both Y/C/Composite mode and RGB mode) accordingly. The
lower the supply voltage is, the lower the pull-down resistance has to be. The ideal resistance values
can be achieved by adjusting the Y/C/Composite output to be 1V peak-to-peak, or the RGB output to
be 0.7V peak-to-peak.
