Introduction Of Ic; Introduction Of Important Function - Sony S75F Service Manual

5.1.2 Introduction of IC

GM5321: integrate ADC, OSD, SCALER, MCU, LVDS, 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:
