8. CIRCUIT DESCRPTION 

A. Micro-Controller Circuit 

The U5 (s9050-100) is a system controller. 

The Y1 is 14.318MHz XTAL. 

 

B.  Circuit of Plug and Play 

Plug and play allows the serial communication of host PC and peripherals offering minimal 
configurations to end users.  This monitor supports DDC2B communication protocal. 

SDATA and VCLK are input to U4 (24LC21A). 

 

C. System Clock 

The Y1 (14.318MHz XTAL) supports U5 (Sage) reference clock. 

 

D.  Image Engine (Zoom) 

The U5 (Sage) is a image engine that have following functions. 

(1) The Sage is a IFM ( Input Format Measurement ) 

(2) The Sage are both high guilty scalar and timing controller chip. 

 

E. Power Regulator 

(1) 

The U12(APL117) is 1A linear regulator that transfer input voltage from 5V to 3.3V 
supports U5. 

(2) The U13(AIC1084) is 5A linear regulator that transfer voltage from 5V to 3.3V supports 

U17 and Panel Vcc. 

(3) The U14 (APL1117) is 1A linear regulator that transfer voltage from 5V to 2.5V. 

(4) The U15 (APL1117) is 1A linear regulator that transfer voltage from 5V to 2.5V.
