TI Announces 16-bit, 10MSPS Delta-Sigma ADC

Texas Instruments announced a 16-bit, 10MSPS delta-sigma analog-to-digital converter - ADS1610 - which features 86dB SNR and 95dB spurious-free dynamic range (SFDR) over a 5MHz bandwidth. The ADS1610 is positioned for demanding measurements in communications, scientific instrumentation, and test and measurement applications.

A 4.4MHz passband with less than 0.0002dB of ripple provides wideband signal processing, while an on-chip digital filter simplifies anti-alias requirements compared to SAR and pipeline converters. The device operates from a +5V analog supply and a +3V digital supply.

The ADS1610 is optimized to work with TI's TMS320TM DSP platforms. It is also pin-compatible with TI's previously introduced ADS1605 (16-bit, 5MSPS ADC) and ADS1625 (18-bit, 1.25MSPS ADC) to provide an easy upgrade path.

The ADS1610 is sampling now, with volume production scheduled for Q3 2005. The device comes in a TQFP-64 package and is priced at $29.95 in 1,000 piece quantities (suggested resale pricing). Evaluation modules are also available.

TI Introduces New Aureus DSPs And Software Library

Texas Instruments introduced new solutions in its Aureus family of audio digital signal processors (DSPs) for applications requiring multi-channel decoding, including audio/video and DVD receivers, home-theater-in-a-box systems (HTIBs), set-top boxes, mini-compos, high-definition televisions (HDTV) and automotive navigation/multimedia systems.

The new 300 MHz TMS320DA710 and 250 MHz TMS320DA708, according to the vendor, offers 50% performance improvement at the same price point as the previous generation of Aureus products. A complete 7.1 system, including AC3 or DTS decoding, Dolby ProLogic IIx or NEO:6 matrix decoding, bass management, and delay, is claimed to take only 22% of the available performance of a DA710 processor.

The list of improvements includes architectural enhancements, new mixed-precision instructions, audio-optimized Dual Data Movement Accelerator (DMAX), CPU core and memory subsystem enhancements, and the increased amount of parallel processing.

DA7xx devices are backed by TI's Performance Audio Software Library, an end-to-end system software solution that includes:

• Industry-standard decoders and post-processors from Dolby, DTS and THX
• MP3, WMA and ATRAC3plus encoder and decoder modules
• Double-precision (64-bit) Bass Management
• The TI Effects Library, which includes configurable modules for Graphical EQ, Room Simulators and Matrix Decoders
• Optimized filter blocks for building custom algorithms
• Bitstream auto-detection, system framework and I/O drivers.

The Performance Audio Software Library is based on TI's XDAIS algorithm standard, which allows OEMs and third parties to create plug-and-play algorithms.

Currently sampling, both devices are slated for volume production in Q3 2005. The 250 MHz TMS320DA708 costs $13.52 each and comes in a 144-pin TQFP package. The 300 MHz TMS320DA710 costs $21.63 and comes in a 256-ball BGA package, both in 10,000 unit or more quantities.

Fujitsu Siemens Computers Offers New Opteron-Based Workstations

AMD today announced that Fujitsu Siemens Computers is offering a new series of workstations based on the AMD Opteron processor. In particular, CELSIUS V830 supports the Dual-Core AMD Opteron processor Models 275, 270 and 265.

The CELSIUS V series offers system performance up to 32 GB DDR SDRAM. The CELSIUS V830 model consists of a RoHS-compliant base unit and an improved housing and thermal management system over prior Fujitsu Siemens Computers workstations. According to the vendor, this leads to about 50% noise-level reduction.

New workstations support AMD PowerNow! technology with Optimized Power Management that can reduce power consumption in enterprises by dynamically changing power states based on workload utilization.

The CELSIUS V830 also uses the NVIDIA´s nForce Professional 2200 and 2050 MCPs along with the AMD-8132 chipset component HyperTransport technology PCI-X 2.0 tunnel and offers two x16 PCI Express ports supporting SLI.

The new Fujitsu Siemens Computers CELSIUS V830 will be available in single- and dual-core configurations starting in August 2005 in Europe, the Middle East and Asia.
