The RK3066 HDMI TX serves as interface between a LCD Controller and a HDMI bus. A HDMI TX consists of one HDMI transmitter controller and one HDMI transmitter PHY. The interface has three (3) 8-bit data channels which can be configured for a number of bus widths (8/10/12/16/20/24-bit) and different video formats (RGB, YCbCr). Features: HDMI version 1.4a, HDCP revision 1.4 and DVI version 1.0 compliant transmitter. Supports DTV resolutions from 480i to 1080i/p HD. Master I2C interface for a DDC connection. HDMI TX supports multiple power save modes. The HDMI TX input can switch between LCDC0 and LCDC1.
