1 General Description
The QCA7500 HPAV2 Compliant MAC/PHY Transceiver is a System-on-Chip (SoC) designed to
bridge multi-stream Ethernet content from a powerline network to an Ethernet 802.3 network.
Examples include high and standard definition television (HDTV, SDTV), and other digital
multimedia file sharing and data applications. The powerline communications (PLC) specific
MAC manages network admission and service flows to maximize the quality of service (QoS)
over the powerline network.
