TI Introduces First HDTV Compliant Digital-to-Analog Converters; Automatic Tri-level Sync Pulse Generation Eases Design and Brings HDTV Products to Market Faster DALLAS, March 29 /PRNewswire/ -- Two new digital-to-analog converters (DACs) from Texas Instruments (NYSE: TXN - news; TI) are the industry's first specifically designed for High Definition Television (HDTV) set top boxes (STB) and other video/graphics applications like professional video editing, mixing and broadcast equipment, PC graphics, medical imaging and desktop publishing systems. By automatically generating the analog tri-level synchronization signals specified in HDTV standards, these devices simplify the HDTV systems design and reduce the cost of HDTV systems, and bring such systems to market faster. Because of a flexible input interface, these DACs can interface efficiently with a wide range of DSPs including TI's TMS320C6000 platform, which is used extensively in video and graphics applications. ''These DACs are the first in the industry to meet the requirements for HDTV. They also expand on TI's industry-leading line of high-speed data converters that are targeted for digital imaging applications,'' said Tom Lahutsky, New Product Development Manager for TI's Data Converter Products. ''An STB or video equipment system designer will find these new DACs extremely important because they make his job easier. With these devices, a designer can eliminate the discrete analog components that, until now, have been needed to generate the tri-level sync pulses required for HDTV.'' THS8133/34 Support The new devices, which are designated the THS8133 and THS8134, are 10 and 8-bit triple DACs, respectively. They are specified for sampling rates up to 80 mega-samples per second (MSPS), which supports the 74.25 MSPS requirements of HDTV. Both devices are fully compliant with the HDTV video standards as defined by EIA 770-3 and the Society of Motion Picture and Television Engineers (SMPTE-274 and SMPTE-296). Each device features three DACs in the same small package, internal voltage reference and current output capable of driving loads down to 37.5 ohms. Additionally, they have configuration control logic for generating either a traditional bi-level synchronization signal or the tri-level synchronization signal needed for handling the component video signaling of HDTV. Both devices are specified for 5V analog and 3V to 5V digital supplies, and dissipate only 515mW of power typically. The integrated configuration control logic of the THS8133/34 devices allows them to handle various input modes in conformance with several professional standards such as ITU.BT-656 and -- 601, which are used in broadcast-quality video mixing and editing systems. The higher 10-bit resolution of the THS8133 makes this device well suited to professional video systems, while the 8-bit THS8134 is optimized for the more cost-sensitive consumer products. TI Expands Its High-speed Data Converter Line with 3V ADC TI has also introduced a new high-speed data converter that operates from 3V supply, which will enhance power-sensitive applications. The TLV5580 is a low-power 8-bit analog-to-digital converter (ADC) that has a sampling rate of 80 MSPS. This device reduces power consumption compared to equivalent 5V solutions, while still delivering 41.5 dB minimum of signal-to- noise+distortion ratio. The TLV5580 has no missing codes and differential non-linearity of < 1LSB. It is well suited for applications such as flat panel displays, DVD players, over-sampled video, communications demodulators, copiers and digital cameras. Evaluation Modules Assure Rapid Development An evaluation module (EVM) for the THS8133 and the THS8134 is available to help designers appraise the performance characteristics of each device. EVMs are also available for the TLV5580. Pricing and Availability The THS8133/34 devices come in the same, pin-for-pin compatible 48-pin thin quad flat pack (TQFP) PowerPAD(TM) package and are sampling now from TI and its authorized distributors. Production quantities are planned for May 1999. Suggested resale pricing in quantities of 1,000 is $8.50 for the THS8133 and $6.50 for the THS8134. The TLV5580 is available now from TI and its authorized distributors. The device comes in a thin scale small outline package (TSSOP) and a small outline (SOIC) package. Suggested resale pricing in quantities of 1,000 begins at $5.38. The THS8133/34 evaluation module is available now from TI and is priced at $230.
