The MT2170 is the industry's first 1GHz input tuner based on the CableLabs DOCSIS 3.0 specification. Developed by Microtune, this tuner chip is engineered to deliver the data speeds (greater than 160Mbps), and wider bandwidth (100MHz) demanded by cable equipment manufacturers for an easy, reliable, and cost-effective way to implement DOCSIS 3.0.
The MT2170 tuner offers the equivalent functionality of four DOCSIS 2.0 digital tuners in a highly integrated miniature package, shrinking the tuner footprint and reducing the power consumption by approximately 75% compared to pre-DOCSIS 3.0 multi-tuner solutions. The tuner also reduces the radio frequency (RF) bill of materials costs.
The MT2170 is engineered to function in a much more hostile signal environment than that experienced by conventional cable modem tuners. While a conventional cable modem tuner need only process a single stand-alone 6 MHz channel, the MT2170 is able to process wideband bonded channels in the presence of multiple interfering signals, while at the same time meeting stringent DOCSIS 3.0 sensitivity and adjacent channel interference requirements.
