Hitron Technologies Inc. and MaxLinear Inc. have announced that Hitron will be using MaxLinear's MxL261 digital cable multichannel tuner-demodulator single-chip front end IC for its DOCSIS 3.0 modems, EMTAs and gateways for European cable markets.

Hitron's CDA-30360 modem recently achieved certification from CableLabs while its CVE-30360 Voice & Data and CDE-30364 Data Wireless Gateways recently achieved EuroDOCSIS certification from CableEuropeLabs in Europe. All models were designed using the MxL261 and Intel Puma 5 chipset. The modem features a 10/100/1000Mbps Ethernet and full IPv6 support. The gateways include USB host interfaces for printer server, NAS file server connectivity or future webcam functionality. The gateways have advanced features including voice and video support, IPv6 routing including DS-Lite and 6RD support.

The MxL261 is based on MaxLinear's low power digital CMOS process-based RF and mixed signal technology. It is a single-die, global standards, digital cable front end with integrated splitter, two 100MHz wideband tuners, four QAM demodulators, and a four-channel wide IF output. The MxL261 delivers ultra-low power at less than 175mW per channel in full eight-channel mode. The low power consumption and the power control flexibility of the chip enable compliance with Energy Star and the European Code of Conduct for Digital TV Services and Broadband Equipment for both standby and operating modes. The MxL261 die is mounted in a 7x7mm, 48-pin QFN package.
