CAT6613 Datasheet
Functional Description
The CAT6613 is the 2nd generation HDMI transmitter and provides complete solutions for HDMI v1.3
Source systems, supporting processing and transmission of Deep Color video and state-of-the-art
digital audio such as DTS-HD and Dolby TrueHD. In addition to the standard color depth and formats
supported by the previous generation (namely the CAT6611), the CAT6613 supports color depths of
10 bits and 12 bits up to 1080p. Advanced processing algorithms are employed to optimize the
performance of video processing such as color space conversion and up/down sampling. The
functional block digram of the CAT6613 is shown in Figure 1, which describes clearly the data flow.

Video Data Processing Flow
Figure 3 depicts the video data processing flow. For the purpose of retaining maximum flexibility, most
of the block enablings and path bypassings are controlled through register programming. Please refer
to CAT6613 Programming Guide for detailed and precise descriptions.
As can be seen from Figure 3, the first step of video data processing is to prepare the video data
(Data), data enable signal (DE), video clock (Clock), horizontal sync and vertical sync signals
(H/VSYNC). While the video data and video clock are always readily available from input pins, the
