PM4381 Analog Front End for ADSL2+
www.DataSheet4U.com
PRODUCT OVERVIEW
The PM4381 Analog Front End (AFE) is a highly integrated solution for
Customer Premises Equipment (CPE) ranging from standalone
modems to Residential Gateways. The PM4381 AFE is suitable for
ADSL2+ CPE, and is fully backwards compatible with ADSL2 and ADSL
interface technologies.
The PM4381 AFE achieves industry-leading performance giving DSL
service providers the ability to offer faster broadband connections
over farther distances. The high degree of integration allows DSL box
vendors to build CPE products with lower BOM cost, and in more
attractive, smaller form factors.
The PM4381 integrates a high performance 5V line driver and offers
extremely low distortion and noise in both transmit and receive paths.
The low noise and distortion, 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), and an optional
1.8V regulator that allows the PM4381 to be used in a system that
only provides 3.3V and 5V.
The PM4381 AFE implements PMC-Sierra's AVIS (ADSL2+/VDSL2
Interface Specification) digital interface, which allows flexible
connection to a variety of Discrete Multitone (DMT) processors,
including PMC-Sierra's MSP7120 ADSL2+ Residential Gateway (RG)
SoC.

BENEFITS
Preliminary
Product Brief
Enables industry-leading rate versus reach performance
Full backwards compatibility to ADSL2 and ADSL
High integration, eliminating the need for a discrete line driver and
external power supply and clock components, thereby reducing
BOM costs and real estate.
AVIS flexible digital interface reduces pin-count and provides
compatibility with a wide range of ADSL DMT processors, including
PMC-Sierra's MSP7120 ADSL2+ RG SoC.
