The MT1570 is a highly linear RF amplifier chip for DOCSIS 3.0 upstream channel-bonded communications. (Channel bonding is a DOCSIS 3.0 bandwidth expansion technique that combines multiple channels to significantly increase data rates.) The MT1570 amplifies four data channels from the user device to the cable head-end. Specifically designed to meet the stringent transmit-noise and linearity requirements of the DOCSIS 3.0 specification, it quadruples upstream data rates to 120 Mbps.
The MT1570 also offers excellent distortion performance and output-noise performance. It provides for increased reliability, quality and integrity of bandwidth-intensive upstream data, whether formatted as video, voice or data.
For consumers, these technical parameters translate into decreased upload time, reduced latency in voice-over-IP calls and increased service reliability. Integrated into a very small 5mm x 5mm QFN 20-pin package, the MT1570 provides backward compatibility and coexistence with legacy DOCSIS equipment. It eliminates the requirement for new cable infrastructure investment, providing a cost-effective, low-power strategy to DOCSIS 3.0 and beyond. A MT1570 Product Brief is available on Microtune’s website.
“We pride ourselves in being the performance and market leader in silicon TV tuners, as evidenced by the fact that we have already shipped more than 112 million MicroTuner(TM) tuner chips,” said Mr. Fontaine. “Our upstream amplifier products are as industry-hardened as our silicon TV tuner technology. In fact, to date we have shipped more than 62 million broadband amplifier chips to our brand-leading OEM customers.”
