Pericom Rolls Out Two Spread Spectrum Clock Generator/Synthesizers Targeting Video and Graphic Applications


SAN JOSE, Calif., Dec. 5 / -- Pericom Semiconductor Corporation (NASDAQ:PSEM), a worldwide preferred supplier of high-speed integrated circuits and frequency control devices, has broadened its Total Timing Solution portfolio with two new spread spectrum clock generator/synthesizer IC's that are ideal for EMI reduction in external video and graphic chipset applications that require down-spread such as Intel® Centrino(TM) mobile PC's based around the Intel "Napa" platform.

PI6C3420 and PI6C3421 are precision 27MHz spread-spectrum clock generators that accept a 14.318MHz crystal or 14.318MHz reference input to generate a 27MHz clock and a 27MHz clock with spread-spectrum. Pericom holds an industry advantage in that this advanced solution does not require a separate 27MHz crystal or 27MHz reference as does competitor devices because it takes the signal from the main motherboard clock.

"By using Pericom's unique 3420/3421 clock solutions, our video and graphic customers will see tremendous cost savings, as well as significant savings in both board space and design time when compared to alternative solutions that are currently on the market," said Kay Annamalai, Senior Director of Clock Marketing, Pericom Semiconductor. "Both the PI6C3420 and PI6C3421 feature better EMI reduction performance from Hershey-Kiss spread spectrum technology, and hardware strapping for spread spectrum control."

PI6C3420 and PI6C3421 operate off 3.3V +/-10% power supply, and are guaranteed over the commercial temperature range (0 degrees C to +70 degrees C). Total generated short-term jitter performance is guaranteed to be less than 350ps.
