ES7120 HDMI Transmitter Product Brief PRELIMINARY ESS Technology, Inc. DESCRIPTION The ESS ES7120 HDMI Transmitter was designed to connect ESS’ DVD Decoder ICs to HDTV TVs. The ES7120 transports high-definition Digital Video and multichannel Digital Audio over a TMDS interface to highdefinition TV displays. The ES7120 contains a Link and PHY and complies with the HDMI 1.1 (High Definition Multimedia Interface) and HDCP 1.1 (High-Bandwidth Digital Content Protection) specifications. This IC provides a simple, low cost and high quality method of sending protected digital audio and video, providing end users with a truly all-digital experience. The ESS DVD player ICs can transmit the highest quality digital audio and video content over a simple, low cost cable to high resolution TVs and displays. At the same time, built in backward compatibility with DVI 1.0 allows the ESS HDMI ICs to connect to any DVI 1.0 display (DTV, plasma display, LCD TV, PC monitor). The ES7120 incorporates an extremely flexible audio and video interface. An integrated color space converter allows direct connection to ESS DVD Decoder ICs via their 12 bit YCbCr and 8-bit BT 656 outputs. An industry standard S/PDIF accepts PCM encoded data as well as Dolby Digital, DTS and other formats capable of being sent over S/PDIF. Four I2S inputs support DVD Audio and decoded Dolby Digital input, enabling pure digital audio connection to A/V receivers. The ES7120 comes pre-programmed with HDCP keys, greatly simplifying the manufacturing process, lowering costs, and providing the highest level of HDCP key security available. ESS provides a reference design with necessary software mo dules to provide a complete solution for HDMI Transmission from DVD Players to HDTVs. ESS Technology, Inc. The ES7120 HDMI transmitter is available in an 80-pin Thin Quad Flat Pack (TQFP) package.
