IC is first to support multi-Gbit MoCA 2.5 for home networking
Claimed to be the world’s first fully integrated circuit to support the multi-gigabit Multimedia over Coax Alliance (MoCA) 2.5 standard that provides at least 2.5Gbit/s of aggregate MAC throughput, the MxL3710 has been announced by MaxLinear.
Operators are investing in the network infrastructure to bring 1Gbit/s and higher data-rate services to home subscribers. This in turn creates the enormous challenge of distributing the received multi-gigabit WAN data bandwidth seamlessly throughout the home. MoCA 2.5 addresses the critical need of matching the capacity and reliability of in-home LAN networks to that of the WAN, thus eliminating bottlenecks to high speed data distribution inside the home.
The IC provides 2.5Gbit/s of MAC throughput over a 16-node home network consisting of other MoCA 2.5 devices. An enhanced mode enables it to achieve up to 3.0Gbit/s of throughput when communicating with other MxL3710 nodes in the same network. The IC is backward-interoperable with any MoCA 1.0, 1.1 and 2.0 standards-compliant devices.
The single chip contains an integrated RF power amplifier (PA), Tx/Rx switch functionality, low-noise amplifier (LNA), Full-Spectrum Capture (FSC) ADC, MoCA PHY and MAC. Supported interfaces include 2.5G SGMII and PCIe v2.1 (MxL3711). For MoCA adapters, a host-less version of the chip is also available to provide the lowest possible bill-of-material cost.
The 8.0 x 8.0mm QFN package is pin-compatible to the company’s MoCA 2.0 bonded IC, the MxL3705, which delivers up to 1.2Gbit/s of MAC throughput.
