Philips offers HDMI-Compliant Receiver and Reference Design for Next-Generation High-Definition TVs


San Jose, Calif., February 22, 2005 - Royal Philips Electronics (NYSE: PHG, AEX: PHI) today unveiled a high-definition multimedia interface (HDMI) receiver integrated circuit (IC), the TDA9775A, to meet consumer demands for superior image quality in next-generation TVs. A reference design is also available with the new receiver IC. Philips' TDA9975A HDMI receiver will allow TV manufacturers to combine uncompressed high-definition video and multi-channel audio through a single digital interface and a tiny, user-friendly connector. For consumers, HDMI technology not only offers crisp image quality, but the use of a single cable for both audio and video that dramatically simplifies home theater system installation.

Philips' TDA9975A, implemented in a reference design, successfully passed the HDMI 1.1 Compliance Test Specification. It is the only receiver on the market that offers a low-power combination of a triple 10-bit analog-to-digital (ADC) input interface, dual-input HDMI receiver and High-bandwidth Digital Content Protection (HDCP) decryption keys on a single chip. All these on-board features extend space and cost savings, and allow TV manufacturers to simplify the design of a TV accepting both state-of-the-art digital HDMI input signals and legacy YPbPr/RGB analog signals. The higher integration and low power consumption of the receiver also contribute to the lifetime of TV sets.

"HDMI is overtaking the digital visual interface (DVI) standard found in CE products like digital TVs, set-top boxes and DVD players due to its multi-channel audio support and smaller connector compared to the DVI specification," said Brian O'Rourke, senior analyst with In-Stat/MDR. "Approximately 3 million TV sets were installed with HDMI connectors in 2004, accounting for 18 percent of the digital TV market share. By 2006, HDMI is expected to be installed in approximately 20 million TV sets, bumping its market share to 42 percent."

"Philips' highly-integrated receiver will enable TV manufacturers to quickly and effortlessly ramp up production of high-definition TVs to meet the latest HDMI specifications and at the same time remain compliant with all analog standards - from PAL/NTSC interlaced to 720p and 1080i HDTV," said Bertrand Woestelandt, Philips Semiconductors' HDMI strategic marketing manager. "Philips' TDA9975A receiver ensures high-definition TVs retain the highest possible video quality from the source right up to the display."

The availability of a reference design for Philips' TDA9975A enables TV manufacturers to include the new HDMI receiver feature in existing systems by optimizing preset input interface architectures, data bus layouts and PCB print complexity and size.

Features of the TDA9975A reference design

The TDA9975A reference design converts HDMI 1.1 audio/video input data streams into analog YpbPr video signals and analog L/R stereo audio signals. This board is supplied with a 7V power supply, and when connected to a 17-inch, HD-ready LCD TV, displays resolutions from 480p/576p up to 720P/1080i. Offering full system support, this reference design is available now and comes with complete software tools, flowcharts, drivers and settings.

Pricing and availability

In addition to the TDA9975A receiver, Philips is offering the TDA9974A, a dual-input HDMI receiver, and the TDA9970A, a combination of a dual-input HDMI receiver and a three-input triple 8-bit ADC. These receivers are pin-to-pin and software-compatible with each other, allowing manufacturers to minimize PCB and software development costs.

These three parts are available now in LBGA256 and SQFP208 packages. In quantities of 10,000 the TDA9975A, TDA9974A and TDA9970A receivers are priced at USD $16, USD $14 and USD $10, respectively.
