2.11 TMDS signal process

2.11.1 Circuit and description

This product uses IC11 (SiL153B) for digital interface, IC14 (24C02) is digital interface DDC data and uses
W06 DVI interface for TMDS signal to IC11. When digital interface D6 is at Low level , Q10 is turned on and
power of IC11 is output through D115 and D116 and the power will support about 3.5V. IC11 generates DE,
CLK, H-Sync, V-Sync and data to AM121-2. When D6 is HIGH and Q10 is turned off, so IC11 will not support
the power. At same condition IC15 (74LS14) Pin 6 will transfer a LOW level and IC11 enters into Power down
status.
