Integrated Circuit Systems Clock Chip Enables TV Output on High-Performance Multimedia Cards; NVIDIA Corp. Selects MK2715-01S Chip To Synchronize Video, Audio Signals For NTSC/PAL Output On RIVA 128-Based Graphics Accelerators

Business Wire, Sept 17, 1997

VALLEY FORGE, Pa.--(BUSINESS WIRE)--Sept. 17, 1997--Integrated Circuit Systems, Inc., (NASDAQ:ICST) today announced that its MK2715-01S clock chip is used by NVIDIA Corp. in the RIVA 128(TM) reference design for integrated 2D/3D graphics cards.

Cards based on this design, and marketed by such companies as STB Systems (NASDAQ:STBI) and Diamond Multimedia (NASDAQ:DIMD), are now shipping on high-performance Pentium(R) II-based systems from major computer manufacturers.

The MK2715-01S is an NTSC/PAL clock chip for desktop graphics applications. It provides the frequencies needed for conversion of computer graphics output to television monitor video rates, conforming to the two international standards (NTSC and PAL) for television signals. This enables graphics accelerator support for both computer and television monitors, a feature that enables manufacturers to differentiate their multimedia personal computers at little additional cost.

The ICS chip is used on RIVA 128-based graphics cards that were recognized by PC Magazine (Sept. 23, 1997; page 105), for high-performance in 3D WinMark tests. The article reviewed 300 MHz, Pentium II PCs with Accelerated Graphics Port technology, including systems from Dell Computer Corp. (NASDAQ:DELL), Gateway 2000 Inc. (NYSE:GTW), and Micron Electronics Inc. (NASDAQ:MUEI), that use RIVA 128-based graphics cards. The cards were the STB Velocity 128 AGP and Diamond Viper V330 AGP. PCI bus cards based on the RIVA 128 also use the ICS clock chip to support video out timing.

"NVIDIA's graphics solutions are designed to provide end-users with maximum flexibility and performance," said Michael Hara, director of marketing at NVIDIA. "This includes integrated 2D and 3D graphics on a single chip and support for video output to any type of monitor. ICS's clock chips play a key role in meeting our design goals, to provide truly innovative multimedia graphics solutions to the consumer market."

"With it's zero ppm synthesis error, the MK2715-01S allows NVIDIA to perfectly synchronize the audio and video on their PCI and AGP based boards," said Barry Olsen, vice president of marketing for the MicroClock Division of ICS. "We are proud to provide a solution selected by the performance leader in integrated 2D/3D graphics acceleration."
