HomePlug Green PHY
Single Chip Solution
QCA7000
The demands of connectivity are growing, but the house is
ready to rock thanks to Powerline technology from Qualcomm.
Copper power wiring provides the most flexible and scalable
spectrum available, capable of reaching virtually any location in
any house. Powerline taps this hidden resource to access today’s
high performance applications and devices, so everyone can
experience the magic. And every home can be a digital home.
Qualcomm AMP. Performance is in the house.
Product Overview
The QCA7000/7005 is the latest addition to the Powerline
Communications (PLC) portfolio of communication ICs from
Qualcomm. It is fully compliant with the HomePlug Green PHY
(HPGP) specification. HomePlug’s Green PHY specification was
developed specifically for energy management applications.
The QCA7000/7005 has the same range and reliability as the
other members of the Qualcomm family of HomePlug compliant
IC’s. However, the QCA7000/7005 has been designed to meet
specific industry requirements for a HomePlug AV interoperable
device that offered lower power consumption, lower product
complexity and reduced BOM costs.
The QCA7000/7005 is fully interoperable with HomePlug AV
and IEEE 1901 compliant products. The QCA7000/7005 features
HomePlug Green PHY Distributed Bandwidth Control to ensure
effective coexistence with HPAV equipment operating in close
proximity on the same power line infrastructure. The IC also
supports HPGP Power Save Mode, which enables the IC to enter
and exit a low power state on a scheduled basis to maintain
network synchronization. The SLAC Protocol is also supported
to enable use of the IC in electric transportation applications.
