SAN JOSE, Calif., USA – April 26, 2010 – Nuvoton Technology Corp., a leading worldwide provider of semiconductors for consumer and computing applications, today announces the expansion of its next-generation Pro-X (PROgrammable Extended CODEC/SLCC) Series devices with the introduction of the N681622 Subscriber Line Control Circuit (SLCC). Supporting one Foreign eXchange Station (FXS) ports, the N681522 operates seamlessly with Nuvoton's recently introduced single-channel and dual channel Pro-X CODEC/SLCC devices -- the N681386 for narrowband (8kHz) operation and N681387 for wideband (16kHz) operation, as well as the dual-channel the N682386 (narrowband) and N682387 (wideband).

In the past, these four devices required an external analog front-end (AFE) consisting of discrete devices. The N681622 now integrates all the AFE transistors needed for a single-channel FXS into one low-cost package. The resulting chipsets can be implemented in a variety of FXS solutions: single- and dual-channel, narrowband and wideband. The N681386 and N681622, for example, can be used to implement a single narrowband FXS solution, while the N682387 and two N681622s can be designed into dual-wideband FXS solutions.

By integrating discrete AFE components, the N681622 reduces total component count of a design up to 30 percent which yields corresponding inventory savings for manufacturers and reliability improvements for end users. Additionally, the board space used by AFE devices can be reduced by more than half, making far more compact solutions possible. Furthermore, the N681622's AFE implementation reduces the designs' power consumption in all states, including over 20 percent improvement in the On-Hook state.

The N681622 extends the Nuvoton Pro-X architecture's objective of distributing temperature gains evenly across the circuit design, ensuring that no "hot spots" develop within end-user systems. By keeping each Subscriber Line Feed Circuit (SLFC) channel in separate packages with individual heat sinks, Nuvoton provides engineers with more options to control temperature -- even in the most challenging environments.

"The N681622 builds on Nuvoton's unique, widely deployed Pro-X architecture with a more highly integrated, complementary CODEC/SLCC that dramatically reduces power consumption, component count and board space in a wide range of FXS applications," said Saleel Awsare, president, Nuvoton Technology Corp. America. "Furthermore, this new device maintains Nuvoton's industry-leading audio performance benchmarks that deliver superior voice quality."

The Pro-X family's CODEC/SLCC and SFLC combination enables a low typical Idle Channel Noise (ICN) -- as low as 3dBRNC -- and typical Return Loss of 40dB. These features directly translate into superior Voice Quality Test (VQT) scores for end-user systems.
