1 General Information
1.1 Description
The QCA7000 is the latest addition to the Powerline Communications (PLC) portfolio of
communication ICs from Atheros. It is fully compliant with the HomePlug Green PHY (HPGP)
specification. HomePlug's Green PHY specification was developed specifically to meet the needs
of the home, utility and Smart Grid applications. The QCA7000 uses a robust OFDM (ROBO)
mode of communication that provides extended coverage and reliable communication over
Powerline networks. However, the QCA7000 has been designed to meet specific industry
requirements for HomePlug AV compatibility. The QCA7000 is interoperable up to the HPGP
maximum data rate of 10 Mbps and offers lower power consumption, lower product complexity
and reduced BOM costs.
The QCA7000 is fully interoperable with HomePlug AV and IEEE 1901 compliant products. The
QCA7000 supports HomePlug Green PHY Distributed Bandwidth Control to ensure effective
coexistence with HPAV equipment operating in close proximity on the same Powerline
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.
An integrated switching power supply provides the 1.2 V core voltage. No external active
components are required. Inductors and capacitors are required for the bypass circuit.
1.2 Features
Compliant with HomePlug Green PHY specification
Interoperable with HomePlug AV specification and IEEE 1901 Standard up to the maximum
HPGP data rate
Operates on 240 VAC, 120 VAC, 24 VAC, and DC lines
Single chip solution with integrated analog front end and line driver
Lower cost and power consumption than existing HPAV solutions for lower data rates - ideal
for Smart Grid applications
Industrial temperature range for extended temperature and smart meter applications
Requires QCA7000 HomePlug Green PHY Firmware v1.0.0-07 and higher
Host interfaces: SPI (Slave) and UART
Boot from host or external FLASH memory
Dedicated FLASH memory port (SPI master)
Supports Robust OFDM (ROBO) mode modulation: 4 Mbps to 10 Mbps PHY rates
Powered from single 3.3 VDC rail with integrated Power Management Unit
RoHS Compliant: 8 x 8 mm 68 pin QFN
