The TDA8754 is a triple 8bit video data convertor optimised for use in LCD monitors, projectors and televisions.

The TDA8754 is a triple 8bit video data convertor optimised for use in liquid crystal display (LCD) monitors, projectors and televisions.

The TDA8754 converts RGB/YUV signals from virtually any analogue source into digital data.

The TDA8754 then digitally processes the data for use in high-speed flat panel displays with resolution up to QXGA (2048 x 1536 at 85Hz) and high-definition televisions (HDTVs) - eliminating the need for external components for processing data.

This integrated functionality reduces component costs and simplifies the design process.

Digital display systems are experiencing rapid growth, with In-Stat MDR predicting 30% growth for LCD PC monitors and business projectors and 60% growth for digital TV monitors between 2002 and 2007.

With the proliferation of digital display systems, there is the need for devices that support the transition from analogue to digital.

Philips is enabling this transition by offering systems that support both analogue and digital standards as well as devices such as the TDA8754.

With two analogue inputs, a wide speed range and robust sync processing for compliance with all analogue video formats, the TDA8754 provides customers with a flexible solution for converting analogue video signals under 8bit into triple 8bit parallel data streams for quality digital pictures.

"Leveraging its expertise in TV and LCD systems, Philips has optimised the TDA8754 for video and graphic displays such as LCD TVs - which Philips sees as a key device for the connected home", said Bertrand Woestelandt, Video Marketing Manager at Philips Semiconductors.

"The TDA8754 will provide these systems with high resolution digital video, bridging the gap between the analogue and digital world".

In addition to offering the highest digitisation speeds on the market (from SVGA up to QXGA 85Hz) and robust sync processing, Philips' TDA8754 also features low phased lock loop (PLL) jitter for high accuracy sampling and picture quality.

The integrated ADC shows outstanding performances such as an effective number of bits (ENOB) of 7.6bit and a differential nonlinearity (DNL) of 0.25LSB at a clock frequency of 270MHz and input frequency of 10MHz.

Other features include frame and field detection, full operation at +3.3V and low power dissipation.

The TDA8754 also comes in a package with a footprint of 17 x 17mm, the smallest footprint on the market for these types of devices.

The Philips TDA8754 is currently available in LQFP144 and LBGA208 packaging.

The LBGA208 package is pin compatible with Philips' TDA8756.

The TDA8756 offers the same functionality as the TDA8754 with the additional benefit of a DVI receiver that includes high-bandwidth digital content protection.
