Zarlink and 5V Technologies Demonstrate Collaborative Solution that Improves VoIP Voice Quality at COMPUTEX TAIPEI 2007

    - Zarlink voice processing technologies and 5VT SOC (system-on-chip)
      solutions showcased at COMPUTEX TAIPEI (TWTC Hall 3 -
      Booth #G558, June 5-9, 2007)
    - Reference design for IP phones with high-quality speakerphone
      capability available

    OTTAWA, June 4 /CNW Telbec/ - Zarlink Semiconductor Inc. (NYSE/TSX:ZL)
today announced that it is demonstrating its latest hands-free voice
processing products with 5V Technologies Ltd., a fabless developer of complete
SOC solutions for a range of applications in the broadband communications
market, at COMPUTEX TAIPEI 2007 in Taiwan (TWTC Hall 3 - Booth #G558).
    The Zarlink and 5V Technologies solution combines their respective voice
enhancement and IP phone expertise to allow equipment manufacturers to rapidly
evaluate and develop cost-effective IP phones sets supporting high-quality
speakerphone capability. The solution integrates Zarlink's high-performance
acoustic echo canceller technology and 5VT's cost-effective ARM9-based VoIP
SOC (5VT13XX Series). This solution is available as a reference design for
qualified customers.
    Zarlink's ZL(TM)38004 voice processing platform helps solve quality
concerns that have plagued voice-over-IP equipment. The platform is based on
the same technologies currently deployed in telecom applications, where voice
quality is an absolute requirement. This proven expertise allows hands-free
and IP-based communication equipment manufacturers to ensure reliable voice
    The fully featured ZL38004 platform combines Zarlink's voice processor
engine with dual channel wideband, CD quality codecs, on-chip memory and
ZLS38502 firmware for speakerphones. ZLS38502 firmware incorporates unique
noise reduction and echo cancellation techniques to allow equipment designers
to overcome distortion, echo and double-talk issues that plague speakerphones.
    "The combination of Zarlink's ZL38004 platform and the 5VT SOC device
provides manufacturers with a ready-made solution that improves voice quality
in VoIP phones," said Andrew Faulkner, director of Zarlink's Voice Processing
product line. "Many of our target applications, particularly IP-phones, use
ARM-based SOCs for packetization, VoIP SIP Stack implementation and to provide
feature phone functionality. Unfortunately this often leaves too few MIPs for
true full-duplex, high-performance acoustic echo cancellation. Combining 5VT's
SOC solution with the Zarlink ZL38004 platform allows customers more easily
design enriched feature phone sets with high-quality voice performance."
    "Customers will benefit from 5VT and Zarlink's collective expertise - a
proven and cost-effective VoIP SOC along with high-quality acoustic echo
cancellation usually associated with higher-end, expensive VoIP phone sets -
offered as a near-turnkey solution with direct support from both companies,"
said Jackson Chang, CEO, 5V Technologies Ltd.
    Using the powerful 300MHz ARM9 processor with integrated peripherals
specialized for CPE applications, 5VT has been recognized to be a ubiquitous
chip supplier for applications including IP phones, VoIP ATAs, VoIP gateways,
VoIP WLAN gateways, 802.11n WiFi AP routers and other IADs (integrated access
devices). In production for over a year, the 5VT1310, 5VT1312 and 5VT1314
devices have enabled many cost-effective designs while maintaining reliable
performance. Each device is tailored and packaged for a specific purpose.

    IP Phone Reference Design

    The Zarlink and 5VT solution is available as a reference design to
qualified customers. The reference design outlines requirements for a basic IP
phone with speakerphone capability. The design includes two Ethernet ports,
along with an IP bridge supported by 5VT's SOC, expanded keypad and either a
parallel or serial LCD module interface. The reference design can be easily
modified to support feature-rich IP phones. For more information, please send
