Introduction The Sil9135/Sil9135A HDMI Receiver with Enhanced Audio and Deep Color Outputs is a second-generation dual-input High Definition Multimedia Interface(HDMI)receiver. It is software-compatible with the Sil9133receiver, but adds audio support for DTS-HD and Dolby TrueHD. Digital televisions that can display 10-or 12-bit color depth can now provide the highest quality protected digital audio and video over a single cable. The Sil9135and Sil9135A devices, which are functionally identical, can receive Deep Color video up to 12-bit,1080p @60Hz. Backward compatibility with the DVI 1.0specification allows HDMI systems to connect to existing DVI 1.0 hosts, such as HD set-top boxes and PCs. Silicon Image HDMI receivers use the latest generation Transition Minimized Differential Signaling(TMDS) core technology that runs at 25-225 MHz.The chip comes pre-programmed with High-bANDwidth?
