Claimed to be the world's first silicon-based upconverter solution for video-on-demand applications, the VideoCaster solution, developed in partnership with nCUBE Corp., shrinks RF electronics the size of a VCR unit into three miniature chips.

The VideoCaster product, which is made up of the chipset and the production-ready and fully tested MicroModule that houses it, offers a very small upconverter with very low power consumption. It is said to reduce upconverter space by 90 percent, power consumption by 40 percent and costs by 80 percent.

Based on SiGe process technology, a patent-pending architecture and advanced circuit designs, the VideoCaster chipset functions as the "RF portal" to the network in the cable operator's headend. The RFICs take the video signal inputs from multiple sources, enhance and condition them, and then place them in an operator-selectable channel for transmission.

The chipsetcomprised of the MT5011 upconverter, the MT5012 downconverter and the MT1150 driver amplifierhandles 10 streams of digital video.

The three custom-designed RF chips of the VideoCaster solution replace the function of a typical 19-inch rack-mounted unit containing cable headend electronics. Microtune integrates the miniature chipset into the VideoCaster MT5000 MicroModule, which offers a 88.9-by-101.6mm form factor.

The VideoCaster MT5000 MicroModule, including the VideoCaster chipsets, is priced at $1,500 each in quantities of 1,000.
