ARRIS is dialing into a new single-chip tuner design from Microtune Inc. to power its Touchstone Telephony Modem product line.

A single-chip radio frequency tuner, the MicroTuner MT2050, offers a smaller size, lower power consumption and lower cost. ARRIS will use it in its Data Over Cable Service Interface Specification and PacketCable-certified Touchstone TM402 modem series now in production. The modem offers high-speed data access and voice-over-Internet Protocol phone service in one unit.

Gaining the chip supply contract is a big win for Microtune, which is battling with chip giant Broadcom Corp. in the cable modem component market.

"Microtune's MT2050 tuner enables us to meet our VoIP business objective with the quality, performance and low-power demanded of DOCSIS and Packet Cable standards," said Bruce McClelland, ARRIS' vice president of engineering, in a release. "Microtune provides a cost-efficient, stable RF technology that assists us in delivering increased throughput, speed, capacity and reliability in our market-leading telephony modems."
