Low Cost - Approximately 20% to 50% less “cost” than a conventional oscillator equivalent

Fast Delivery - Samples shipped next working day, production quantities shipped in 2 to 10 working days

Low Jitter - Substantially lower jitter & phase noise than Programmable Oscillators and comparable to Fixed Frequency Oscillators

• 1995 - Established semiconductor group– Began development of custom programmable PLL and custom memory

structure technologies

• 1998 – JITO – Focused on fast delivery– Oscillator utilizing the programmable PLL and custom memory structure – Patented frequency tuning allowing for tight accuracy– Streamlined manufacturing processes– 10 day Just in Time delivery method developed

• 2003 – rfXO – Focused on low noise / high performance– High frequency (600MHz~1.25GHz) oscillator utilizing a low noise PLL is

released for the SONET market– Stand-alone patented memory structure developed

• 2007 – XpressOtm – Combining low noise & fast delivery with low cost– Low noise Fractional-N PLL– Patented memory structure– 3rd Order DSM noise dispersion technology with selectable settings based

on customer noise requirements– Streamlined raw material and manufacturing process

• Utilizes multiple custom designed ASICs – Our own non-volatile memory structures – Lowers Cost– Noise-reducing DSM technology – Lowers Jitter and Phase noise– Building block architecture – Allows Fast Delivery– Different functional blocks – Provides Maximum Flexibility

• 6 U.S. and 8 foreign patents issued
