Alliance Semiconductor Offers el-EMI-nator Series IC

September 13, 2004 by Jeff Shepard

Alliance Semiconductor Corp. (Santa Clara, CA) announced the availability of its el-EMI-nator™ Series of PLL-based, electromagnetic interference (EMI) reduction ICs, which allows designers to select from a wide series of configurations, while reducing EMI at the clock source.

The el-EMI-nator Series currently consists of 12 devices with frequency ranges from 6 MHz to 50 MHz, and a variety of frequency deviations and modulation rates. Designed specifically for low power applications where battery life and physical space requirements are an issue, the devices typically consume as little as 8 µA in standby mode, and typically less than 4 mA operating. In addition to the low power consumption, the family is available in the a small footprint, six-lead TSOT23 package with a maximum of 1 mm height, fitting the small footprint requirements for applications like MP3 players, PDAs and other hand-held devices and products.

The el-EMI-nator Series includes a single on-chip PLL with either a single modulated output, or one modulated and one un-modulated REF output, supply voltage ranges of either 2.5 V or 3.3 V with selectable spread range and modulation rates. The full el-EMI-nator Series is currently in production with evaluation boards available now.
