A/D convertor measures smaller signals faster
Sigma-delta ADC achieves greater than true 16bit noise-free resolution up to 2.4kHz across all input voltages from 40mV to 5V.
SAR convertor claims record speed and accuracy
A/D convertor achieves a new level of 16bit data capture performance, with best-in-class 15bit ENOB and 10Msample/s throughput.
As a result, it is ideal for manufacturers creating affordable customer premises equipment (CPE) designed to deliver one or more broadband services - ranging from voice over IP (VoIP), to wireless local-area network (WLAN), to triple-play (voice, data, video) - with the quality of service (QoS) that residential and SOHO customers expect.
Accelerator processors are responsible for the Fusiv-Vx 150 network processor's ability to achieve wire-speed performance even with small packet sizes.
Its accelerator processors handle the routing and QoS functions, freeing the main CPU to run customer-specific applications; scale to new services, such as home automation, gaming, and jukebox functionality; and add customer-friendly interfaces, such as on-screen menus and programme guides.

With on-chip 24bit sigma-delta ADCs, the ADuC706x provides the resolution required by today's high-performance industrial and instrumentation equipment.
"The role of the residential gateway is becoming more demanding as multiservice applications are being rolled out in the market", said John Croteau, General Manager, Media Platforms and Services Group at Analog Devices: "As a member of the Fusiv network processor family, the Fusiv-Vx 150 chipset fills the need for a powerful, scalable network processor able to satisfy this important market segment's ever-growing requirements, plus offering the headroom for future applications".
As a stand-alone processor, the Fusiv-Vx 150 chipset can act as a telephone adapter or Ethernet-to-Ethernet gateway, delivering networked voice and bundled voice and data applications such as VoIP to residential customers.
An integrated digital signal processing (DSP)/voice processing engine handles up to four channels of low bitrate (LBR) codecs.
Optimised voice-chain software supplies voice compression, echo cancellation, packet loss concealment, DTMF, caller ID, and more.
signalling and packetisation software includes SIP, H.323, and MGCP functionality.
The high level of integration achieved by the Fusiv-Vx 150 network processor - that is, combining wire-speed network processing, signalling and full-chain voice processing - can lead to bill-of-materials (BOM) cost reductions of up to 25%.
A variety of wired and wireless network interfaces help CPE manufacturers to implement desirable connectivity options, including WLAN or HomePlug, for use inside the home.
In addition, the Fusiv-Vx 150 processor can be combined with ADI's Blackfin processor to enable greater voice channel density, and to add video processing capabilities including multiformat decoding and encoding.
The Fusiv family also includes the Fusiv-Vx 200 network processor (announced in May 2004), which adds hardware-based IPSec security.
The Fusiv-Vx 200 network processor therefore handles the highly compute-intensive encryption required by VPNs, making it optimal for enterprise gateway applications.
In addition to the network processors themselves, ADI provides customers with multiple software options.
Customers can make use of a comprehensive portfolio of software that includes IPSec/VPN, VoIP signalling, firewall/NAT, network management, IP middleware, routing and switching, SNDCP, and ATM.
Other software options include porting of a customer's own software stack, for which ADI provides a comprehensive board support package (BSP).
Alternatively, software can be provided through select third-party software companies.
The Fusiv-Vx 150 chipset is available in per-unit pricing of $20 in low-volume quantities of 10,000.
