The CS98100 requires five different types of power
supplies for the Plus, internal logic, IO pins, video
DAC-digital and video DAC analog. The PLLs, in-
ternal logic and video DAC digital use 1.8 V supply
voltage. The IO pins and video DAC analog use 3.3
V supply voltage. It is recommended to use good
