PMC-Sierra's PM4380 Device Enables OEMs to Provide VDSL2
Residential Gateways and Modems with Breakthrough Rate/Reach
Performance Characteristics PMC-Sierra, Inc. (Nasdaq:PMCS) today
introduced the PM4380 Analog Front End (AFE) for VDSL2 and ADSL2+
Customer Premises Equipment (CPE). The highly integrated CMOS
device is a stand-alone VDSL2 AFE, enabling Original Equipment
Manufacturers (OEMs) to quickly bring to market VDSL2 modem or
residential gateway products. VDSL2 technology allows Service
Providers to offer significantly faster and more robust broadband
connections to support the deployment of IPTV and other advanced IP
services. By tackling the difficult mixed-signal challenges
inherent to the design of such an AFE, PMC-Sierra enables new
entrants into the rapidly expanding VDSL2 CPE market. The AFE
features: -- Extended rate/reach; -- Full backwards compatibility
to ADSL2+; -- High integration, eliminating the need for a discrete
line driver and external power supply and clock components, thereby
reducing BOM costs and real estate; and -- ADSL2+/VDSL2 Interface
Specification (AVIS) flexible digital interface, which reduces
pin-count and provides compatibility with a wide range of xDSL
Discrete Multitone (DMT) processors. Superior Performance
Accelerates New Service Offerings The PM4380 integrates a
high-performance 5V line driver and offers extremely low transmit
path distortion and noise floor. The receive path, including the
integrated ultra-low noise amplifier, provides an input-referred
noise density of -150dBm/Hz, while high-precision 16-bit data
converters offer best-in-class performance on both receive and
transmit chains. The low transmit and receive noise floors,
combined with high-resolution data converters and integrated
programmable receive equalizer and filters, reduce the need for
complex and costly external filters to achieve optimum rate/reach
performance. In addition, the device integrates a 16-bit digitally
controlled crystal oscillator (DCXO) that provides better than 0.02
ppm frequency resolution, and an optional 1.8V regulator that
allows the PM4380 to be used in a system that only provides 3.3V
and 5V. By offering this leading-edge performance, the PM4380
device enables OEMs to deliver products that provide faster
broadband connections over longer loop lengths. "PMC-Sierra has a
strong history in developing leading-edge mixed-signal CMOS
products for communications applications, and we have capitalized
on this expertise to bring to market a leading-edge family of
robust DSL AFEs," said Dino Bekis, vice president of marketing and
applications for PMC-Sierra's Communication Products Division.
"Together with our recently announced MSP7100 Multi-Service
Processor(R) family, we are delivering breakthrough-performance
semiconductor solutions for the delivery of IPTV and other advanced
IP services over broadband." Cost-effective ADSL2+ Solution
PMC-Sierra today also introduced the PM4381 ADSL2+ AFE. The device
is pin compatible with the PM4380, enabling vendors to produce
cost-optimized ADSL2+ variants. The PM4381 interfaces directly to
PMC-Sierra's MSP7120 ADSL2+ Multi-Service Processor, which
integrates Aware, Inc.'s StratiPHY2+(TM) IP, and provides a
complete chipset for advanced residential gateways and Integrated
Access Devices (IADs). Flexible Digital Interface Specification
Both devices implement PMC-Sierra's ADSL2+/VDSL2 Interface
Specification (AVIS) digital interface, which simplifies connection
to a variety of DSL DMT processors by offering selectable data
rates, clocking modes and control signaling. The AVIS interface
offers a nibble-wide configuration to help reduce pin-count on the
connecting modem chips. To promote compatibility of the digital
interface, PMC-Sierra is offering customers and partners free
access to the interface specification at:

PM4380 VDSL2/ADSL2+ and PM4381 ADSL2+ AFE devices will be available
in Q2 2006. A data sheet for the devices may be found on
PMC-Sierra's web site at http://www.pmc-sierra.com/products/. A
