INT5500 Chip Set
Intellon's high speed powerline chipset INT5500CS is comprised of the INT5500, an integrated powerline MAC/ PHY transceiver, and its companion INT1200, an analog front end IC. The INT5500CS is fully compatible with the HomePlug® 1.0 specifications, and capable of delivering up to 85 Mbps over the power line.
The INT5500CS provides a highly integrated and optimized solution for networking adapters and embedded products. It offers the higher bandwidth performance necessary to drive next-generation home entertainment applications, including standard definition (SD) video distribution, TV over IP (IPTV), digital video recorder (DVR) networking and media center PCs. Other applications include whole house audio, extension and bridging of higher speed wireless technologies such as 802.11x and UWB, and higher data-rate broadband sharing based on technologies such as ADSL2 and fiber to the home.
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 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.
Intellon offers a complete solution for powerline applications using the INT5500CS, including data sheets, reference manuals, configuration utility software and production test capabilities, together with a proven technical support team to shorten customer’s time to market.
The INT5500CS provides two types of host interface for maximum system flexibility:
- An MII PHY (IEEE 802.3u) interface for interconnection to Ethernet controllers
- An MII Host / DTE interface (IEEE 802.3u) for direct connection to an Ethernet PHY
The INT5500CS implements Intellon's patented OFDM technology, which forms the basis for the HomePlug 1.0 specification. Tailored to reliably deliver up to 85 Mbps over the difficult power line communication environment, the chipset combats deep attenuation notches, noise 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. Inclusion of additional modulation schemes (QAM 256/64/16) increases the chipset's capability to attain higher throughput performance.
