5.1.2 Introduction of IC
GM5321:
integrate ADC, OSD, SCALER, TCON, LVDS, RSDS convert analog RGB into digital and
zoom and shrink scaling output to LCD panel.
AIC1084-33M:
DC power convert, used to 5v convert 3.3v.
AIC1084-18CE:
DC power convert, used to 5v convert 1.8v.
5.1.3 Introduction of important function
DC TO DC:
The required power supply are different for each chip, and the voltage of 12v, 5v offered by
PWPC can’t reach the requirement, so we deal with this problem by means of two pieces
of DC TO DC chips (AIC1084-18CM, AIC1084-33CM). The circuit diagrams are as follows:
