MOSAID Maestro Digital Frequency Synthesizer PLL Used in WiQuest Ultra-wideband IC

True fractional PLL enables cost effective UWB interface

Santa Clara, California – June 7, 2006 - MOSAID Technologies (TSX: MSD), and WiQuest Communications Inc., today announced the successful deployment of an ultra-wideband (UWB) chip incorporating MOSAID Maestro™ fractional PLL technology. This system-on-a-chip is a complete UWB MAC and PHY. The chip was designed for high-volume PC and consumer applications and is currently sampling with customers. WiQuest selected the MOSAID Maestro DFS PLL as part of a strategy to produce the lowest power and highest performance UWB IC which fully supports the Certified Wireless USB standard.

"We are very happy with the performance of the PLL to help reduce power and generate accurate critical clocks for our chip's radio and MAC circuits," said Greg Christison, WiQuest Vice President of Engineering. "The wide frequency range and fractional multiplication of the PLL made it very easy to use."

"WiQuest's focus on high bandwidth at low power is key to bringing a commercially viable UWB technology to video and wireless USB applications," said Peter Gillingham, VP and GM, MOSAID Intellectual Property Division. "Our cutting-edge low-power fractional PLL moves UWB a giant step closer to reality for these demanding consumer applications."

About MOSAID Maestro PLLs
The MOSAID Maestro family of PLLs includes delta-sigma fractional-N PLL IP products with an ideal combination of true fractional frequency multiplication and low power, making them ideal for portable electronic, consumer and networking applications. Key features of the MOSAID Maestro family include a small area (0.04mm²), less than 2mW of power, and a fine-grain frequency multiplication capability that enables the PLLs to accurately output any frequency for most applications. Additionally, MOSAID Maestro PLL products are fully integrated, highly programmable, feature low jitter and operate over a wide frequency range - up to 3GHz.
