SAN JOSE , Calif., USA — Nuvoton Technology Corp. is participating in 2008 Taipei Taitronics Autumn Show (Venue:Taipei World Trade Center Nangang Exhibition Hall) organized by TAITRA and TEEMA Oct.7-11. Nuvoton Technology Corp. was spun off as a wholly-owned subsidiary of Winbond Electronics Corp. since July 2008. To inherit the rich pedigree of product design achievements from Winbond, Nuvoton devotes to customers our essential total solutions for Consumer Electronics IC and Computer IC. Nuvoton, a leading supplier of semiconductor solutions to the consumer, computer, communications and electronics products markets, today introduced the industry's first four-channel CODEC/SLIC optimized for short-loop VoIP applications. The newest member of Nuvoton's popular Pro-X (PROgrammable Extended) Series of CODEC/SLIC devices, the W684386 is a highly integrated solution to support four FXS telephone line interfaces on a single low-power CMOS device. The W684386 also delivers the industry's best idle channel noise and return loss performance – benchmarks which VoIP-system makers are making a priority to reduce. 

Optimized for short-loop applications, the W684386 targets the VoIP equipment market, including products such as high-density VoIP gateways, analog telephone adapters, voice-enabled DSL and cable modems, IP-PBX, FTTX systems, and set-top boxes.

"As port densities on VoIP equipment increase dramatically with each generation, system designers are looking for a flexible solution with excellent price and performance benchmarks," said Ike Saeed, Vice President of Marketing of Nuvoton's Mixed Signal Product Center. "The W684386 fills this need with a robust four-channel design that not only reduces system cost but also improves the clarity of the VoIP signals."

Proprietary Technology Delivers Versatility, Low Overhead, User-Friendliness

The W684386 leverages Nuvoton's proprietary CODEC/SLIC architecture, combining four programmable CODECs that enable the device to support a comprehensive set of signaling capabilities for telephone line supervision and control, offload processor overhead and offer designers a user-friendly signal-processing environment. The W684386's four-channel SLIC block supports programmable impedance matching and trans-hybrid balancing ensuring that worldwide compliance can be supported from a single hardware configuration. The W684386 also incorporates programmable DC-to-DC controllers, which allow power consumption optimization on a per channel basis. The device can also support higher-density architectures with external ringing and centralized power options. Nuvoton's proprietary CODEC/SLIC is protected by U.S. Patent No. 7,260,212 issued August 21 2007.

Availability, Pricing

The W684386 is available now in a 128-QFP package, at $4.50 (10K quantities), with full production scheduled for Q2. Three evaluation boards are available, each featuring a different DC-to-DC architecture option (per-channel inductor-based, single transformer-based or external battery/external ringing architecture). Each evaluation board features Nuvoton's user-friendly PC-based Graphical User Interface (GUI). Samples and evaluation boards are available now from local Nuvoton sales offices and the company's authorized representatives.
