Atmel's ATR2406 Equips Eleven Engineering's Multi-Channel Digital Wireless Audio Solution for Wireless Home Theater Applications
Las Vegas, Ces Show (ots/PRNewswire) - Atmel(R) (Nasdaq: ATML), a global leader in the development and fabrication of advanced semiconductor solutions, and Eleven Engineering, a leader in digital wireless audio, announced today the availability of a robust Hi-Fi digital wireless audio solution, the Squeak(TM) 1A platform. The Squeak platform integrates Atmel's ATR2406 2.4-GHz ISM-band single-chip transceiver and the XInC2(TM) wireless processor from Eleven Engineering providing baseband MAC protocol, audio CODEC, and advanced dynamic error correction algorithms. Squeak1A provides robust quality of service and outstanding audio fidelity -- even in the presence of interference sources such as microwave ovens, 802.11b/g networks, and cordless telephones -- at indoor ranges of 15, 25 and 50 meters.
Squeak 1A is available in a low-cost, integrated, mass-production WHAM2-package module for easy drop-in wireless audio solutions where multiple nodes are required. The unique architecture of Squeak 1A allows a single transmitter to communicate wirelessly with up to four independent receivers with selectable end-to-end latency of 15, 16, 18, or 20 milliseconds. Combined with its low cost, this makes Squeak 1A a perfect solution for wireless home theatre and other wireless audio applications.
The ATR2406 has outstanding RF performance: high receiver sensitivity of -93 dBm at an RF data rate of 1.152 Mbps, high adjacent-channel rejection of typically more than 33 dBc, and an RF output power of up to +4 dBm for link ranges of more than 150m in free space. This enables Squeak 1A to achieve a large wireless coverage range with excellent immunity against strong inband interference. The integrated VCO and fast PLL enable the use of Eleven Engineering's intelligent, adaptive, fast frequency-hopping algorithm which detects if other RF systems (e.g., WLAN) are using the same ISM frequency range and finds free frequencies to guarantee a superior sound quality.
Squeak 1A, a complete solution for wireless audio, integrates the ATR2406 and XInC2 with standard Squeak system software and customizable application software. The modules can be configured for either analog or digital input/output and have available general-purpose input/output for custom user interface features.
"Using the high-performance ATR2406, the Squeak 1A is the most compelling industry solution for high-volume wireless audio applications," said Matthias Bopp, General Manager and Senior Director of Atmel's BC Communication. "The ATR2406's specific features such as indoor link range and sound quality will give our customers a competitive edge in the quickly growing wireless audio segment."
"Squeak 1A enables multi-node wireless audio from both the standpoint of technology and that of economics," said John Sobota, CEO of Eleven Engineering. "With Squeak 1A, virtually all wiring problems with home-theater systems can be eliminated."
XInC2 is a 16-bit multi-threaded RISC processor with a MAC protocol, audio CODEC, baseband, DSP functionality and advanced dynamic error correction algorithms, streamlined for wireless audio with eight hardware threads handling up to 100 MIPS (Million Instructions Per Second). The Squeak 1A transmitter takes full advantage of XInC2's advanced baseband capability allowing for 2-, 3- and 5-node systems delivering up to four channels of 16-bit, 48 kHz audio samples to four separate speakers.
Squeak 1A is available in mass production module form. To order Squeak 1A modules, evaluation kits, and reference designs, visit Eleven Engineering's website at www.ElevenEngineering.com.
The ATR2406 is available in an ultra-compact QFN32 plastic package (5 x 5 mm) and is manufactured in mass production, having already shipped millions of units in the past months. Pricing for the ATR2406 starts at US $1.80 in quantities of 10K. Various RF evaluation demo boards and complete evaluation kits including manufacturing data can be ordered via Atmel's local sales offices.
