Realtek Demonstrates Latest PC Peripheral IC Solutions at the Spring 2008 Intel Developer Forum


Intel Developer Forum Shanghai – April 02, 2008 – Realtek Semiconductor Corp., one of the world's leading network and computer peripheral IC providers, will demonstrate its latest R&D achievements at the Spring 2008 Intel Developer Forum (April 02~03, Shanghai). Products to be demonstrated include:
1) Class-D Amplifier ICs
2) High Definition Audio Codecs with embedded Class-D Amplifier
3) Highly-integrated, low BOM, high-compatibility Card Readers
4) Clock Generators with excellent AC performance and very low power consumption

Class-D Amplifier ICs
The ALC113 is a highly integrated stereo Class-D audio power amplifier IC that supports up to four stereo channel inputs and offers flexible adjustment of output gain and volume level via I2C control. The ALC113 supports stereo Bridge-Tied Load (BTL) output, with output power up to 10W per channel, and also supports separate headphone output.

“This is the first stereo Class-D audio power amplifier that integrates an audio multiplexer and headphone amplifier, and combines high power efficiency with high performance and high flexibility”, said Robert Wang, Realtek's audio products manager. “The new Realtek ALC113 provides greatly enhanced sound performance and quality in entertainment notebooks and PCs, multifunction monitors with power speakers, and television and multimedia applications”.

High Definition Audio Codecs with Embedded Class-D Amplifier
The ALC889 is a 7.1+2ch DAC/6ch ADC High Definition Audio Codec offering quality audio performance (DAC 108dB SNR, ADC 104dB SNR). The multi-channel DAC/ADC is the ideal choice for home entertainment PCs, providing support for multi-streaming to enable enjoyment of 7.1-channel audio/movies/on-line gaming, etc, and simultaneous 2-channel VoIP.
The ALC889 complies with the latest Microsoft Windows Vista Premium requirements, and offers DSD (Direct Stream Digital) format support and Full Rate Blu-Ray/HD DVD playback capabilities.

For Intel's Mobile PC Extended Battery Life (EBL) community, we will demonstrate the ALC269 2+2ch DAC/4ch ADC multi-streaming notebook/mobile PC High Definition Audio Codec. The ALC269’s integrated 2W-per channel Class-D Amplifier and built-in Headphone Amplifier cut BOM costs, reduce heat output, and reduce mainboard space requirements for PC makers.
The ALC269 offers power efficiency up to 85% and supports the Intel Low-Power ECR for reduced power consumption and extended battery life in mobile PCs.

Card Readers
The RTS5168 and RTS5181 are high-performance Card Readers with built-in high-speed USB 2.0 device controllers providing a 480Mbps transfer rate and backward compatibility with the 12Mbps USB 1.1 specification.

The RTS5168 is the world's first card reader to integrate a Smart Card reader, IR receiver, fingerprint reader, and NAND Flash card reader. The RTS5181 card reader supports high-speed Memory Stick PRO HG, and Dual SD or Dual MS. With high stability, performance, and compatibility the Realtek card readers are expected to take a strong lead in the PC built-in market, with forecast market share over 70%.

Clock Generators
Realtek's Intel Eaglelake/Montevina platform compliant clock generators for Desktop/Notebook/Server segments feature highly smooth up/down-clocking profiles with ultra low power consumption and excellent AC performance.
Realtek clock generators have been adopted by most major PC and notebook ODMs in Taiwan, and received the approval of most of the worldwide top 10 PC brand name suppliers.

“Realtek product development has covered not only the need for high performance, but also for products that permit the increasing number of mobile devices to provide that performance for longer time between battery charges”, said Realtek's Vice President and Spokesman, Jessy Chen. “Our focus has been extended into every aspect of the user experience as we attempt to fast-forward PC and CE equipment convergence”.

The Intel Developer Forum will take place at the Shanghai International Convention Center (SICC) April 02~03. The Realtek booths are as follows:

  • Showcase booth is GE010
  • EBL Community booth is CE031
  • WUSB Community booth is CE045
