The INT5200 Integrated Powerline MAC/PHY Transceiver is the world’s first complete HomePlug 1.0 solution on a chip.
In addition to the HomePlug1.0 Baseband MAC/PHY core, the INT5200 now integrates all external analog components, including ADC, DAC, AGC, filters and the power amplifier. It removes the need for an external Analog Front End and reduces the system’s bill of materials even further, also improving performance. The INT5200 directly interfaces with the AC coupling transformer in the power supply.
It also provides three types of host interface for maximum system flexibility:
- A USB1.1 device interface for connection to a USB host
- An MII PHY (IEEE 802.3u) / GPSI interface for interconnection to microcontrollers or Ethernet controllers
- An MII Host / DTE interface (IEEE 802.3u) for direct connection to an Ethernet PHY
This ultimate level of integration makes the INT5200 ideal for all cost sensitive embedded HomePlug applications such as desktop computers and media receivers.
The INT5200 implements Intellon’s patented PowerPacket OFDM technology, which forms the basis for the HomePlug 1.0 Specification. Specifically tailored to reliably deliver up to 14 Mbps over the difficult power line communication environment, the IC combats deep attenuation notches, noises sources, and multi-path fading by allocating usable frequencies according to the signal to noise ratio (SNR). Synchronization is achieved in low SNR channels without the use of pilot carriers.
The MAC implements a CSMA/CA scheme with prioritization and automatic repeat request (ARQ) for reliable delivery of Ethernet packets via packet encapsulation. Built-in Quality of Service (QoS) features provide the necessary bandwidth for multimedia payloads including voice, data, audio, and video. A four-level prioritized random access method exists with strict adherence to priority. Segment bursting on the power line minimizes the demands on the receiver resources and maximizes the throughput of the network while still providing excellent latency response and jitter performance. The IC’s contention-free access capability extends this concept of segment bursting to allow the transmission of multiple frames over the power line without relinquishing the control of the medium. Utilizing contention-free access, a single station may act as a controller for the entire network.
Intellon offers a complete solution for powerline communication applications using the INT5200, including a suite of reference designs, data sheets, reference manuals, device driver source code and a production test system together with strong, proven technical support to shorten your time to market.
The INT5200 is available for use in a wide range of settings, including residential (in-home), commercial (offices, apartments, hotels, warehouses), transportation and defense applications.
