CX82100-41

Product Summary

The CX82100-41 is an integrated physical layer transceiver or PHY. It is designed to use existing ac electrical wiring within the home as a networking physical medium. The PHY’s robust performance in the electrically noisy power line channel is due to the use of Orthogonal Frequency Division Multiplexing (OFDM). The CX82100-41’s OFDM technology finds the low noise, low attenuation portions of the spectrum available to it and continues data transmission. The device operates on both +1.8 V and +3.3 V supplies and is packaged in a 144-pin Low Quad Flat Pack (LQFP). The applications of the CX82100-41 include: Residential gateways and home routers, Network home or small office PCs, Enable no wire installation networking for information appliances, LAN gaming, Share DSL or cable modem access, MDU/MTU applications, Embedded applications.
