Development of low operating voltage 2.5th generation MUSE (HDTV) chip set

In 1992 we developed a 2nd generation MUSE chip set containing more than 4.2 million transistors (five video chips and one audio chip). The chip set reduced the number of components to about 115, and power to about 113 compared with older first-generation chip sets. As a result, the cost of the HDTV (MUSE) receiver was cut by about 50%. But demand for even less expensive HDTV (MUSE) receivers is strong. We describe the development of a 2.5th generation MUSE chip set which through reduction of the operating voltages we succeeded in a 50% reduction in power consumption, and a 40% reduction in cost while maintaining compatibility with previous 2nd generation LSIs
