PLC Adapter

Brief Description


Xingtera PLC adapter is a reference design for Xingtera’s XT1200 chipset. It supports ITU-T compliant 25MHz, 50MHz and 100MHz bandplans for power line media. This integrated device combines all the functions of PHY compliant to G.9960 & MAC compliant to G.9961 specifications.  Furthermore, it supports (G.9972) / ISP (Inter-System Protocol) to co-exist with other powerline devices based on the PLC technology. PLC adapter integrates 2-prong power plug and RJ45 connector and is completely plug&play. It works under the following conditions:

• 110 – 240V AC power voltage range
• Any 2-prong or 3-prong power sockets in North America, Taiwan, or Japan; For other countries, an adapter may be required.
• 10/100/1000 Base-T Ethernet on RJ45 with auto-negotiation.
• Pairing button and factory reset button

  • Work in the real powerline environment
  • G.9960/9961 compliant
    • Single-Ethernet port to powerline: 25MHz, 50MHz, or 100MHz bandplan
  • Wideband OFDM modem with 2-25MHz,  2-50MHz, or 2-100MHz BW for power line media and 2-50MHz or 2-100MHz coax media
  • State-of-the-art LDPC error correction algorithm with FEC rate of ½, 2/3, 5/6, 16/18, and 20/21 supported
  • Large dynamic range with robust AGC
  • QoS support with four priority queues
  • Dynamically adaptive modulations for each subcarrier based on  the event-driven channel estimate protocol defined in G.9961
  • PHY layer retransmission to overcome instantaneous impulse noises and guarantee delivery
  • 128-bit AES-CCM security with pair-wise keying support.
  • Support network topology up to 8 nodes.
  • Push-button mechanism for network setup and pairing.
  • Domain master: dynamic topology detection and routing; remote management capability.
  • Low power consumption. Total power consumption of the PLC adapter is sub-3.5W in active operating mode.
