HDMI Transmitter

Product Brief

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 provi de a com plete solution for HDM I

Transmission from DVD Players to HDTVs.

The ES7120 HDMI transmitter is available in an 80-pin

Thin Quad Flat Pack (TQFP) package.
