Page 13: Description Of Block Diagram
DESCRIPTION OF BLOCK DIAGRAM 1. Input Selection Circuit This block is composed of 74LVC257(U5) and peripheral devices. There are two inputs, Analog and Digital H/V Sync. LVC257 IC chooses one input and outputs selected input through sync selection pin (Pin 1). 2. - Page 14 10. Panel-Link Circuit TMDS Transmitter (THC63LVD273, U23) is the IC that receives output digital signal of PW166B-20T (U8) and output to LCD Module. The signal format is Panel-link. LCD Module has Panel-link receiver that is same output of PW166B-20T. This is the best for reduction EMI problem and the number of pin connector. 11.
