FREIBURG, Germany -- Micronas GmbH here today announced plans to begin volume production of a single-chip scan-rate converter for progressive-scan televisions, combining the functions of six other devices and potentially saving 30% of the cost compared to other design solutions.
Micronas said its VSP 94x7B chip will ramp into volume production during the second quarter of 2002. The IC supports the conversion of TV images into progressive-scan formats as required for optimized image quality in NTSC-based television sets. This format will support the use of new flat-panel display technologies, such as liquid crystals displays (LCDs) and plasma screens, the company said.
According to Micronas, no other chip manufacturer currently offers a comparable level of integration for the progressive-scan television function. "This unique single-chip solution will help make progressive-scan TV the standard product for mid-range and high-end consumer markets," predicted Johann Weierer, marketing manager video and graphic at Micronas in Freiburg.
The chip integrates all functions for simultaneous processing of two video channels to serve front-end processing in televisions sets. Integrated video memory (embedded DRAM) provides 8 megabits of storage, and the device supports higher data bandwidths with interfaces to external memories. This bandwidth is needed to enable highly dynamic display formats, such as flicker-free zooming of picture-in-picture (PIP) part images to full images, said the company.
"With the new VSP 94xy family, system manufacturers are able to simplify the system architecture and thereby reduce system and development costs drastically," Weierer said.
Analog and digital interfaces for connecting the display processor are located at the chip's output.
The VSP 94x7B operates with 3.3- and 1.8-volt power supplies. The chip will be available in a P-MQFP80 and P-MQFP144 package at a cost of below $30 in high quantities.
