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 multi-
channel Digital Audio over a TMDS interface to high-
definition 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.
