Introduction

  • Purpose

  • To introduce Fox Electronics XpressO Oscillator Technology

  • Objective

  • Showcase XpressO’s cutting edge Technology and how it can solve all of your Oscillator & VCXO timing requirements with superior performance, Reduced cost and lead times measured in days not months.

  • Content

  • 10 Slides

  • Learning time

  • 7 Approximately Minutes


Oscillators......

  • 750 kHz to 1.35 GHz

  • 2.5V / 3.3V Operation Available

  • Stabilities of 20 / 25 / 50 / 100 ppm available

  • 0 to +70C / -40 to +85C Temperature options

  • HCMOS / LV-PECL / LVDS outputs available

  • Industry standard footprints

  • Low jitter for Ethernet, SONET, Fiber Channel, etc.

They Change Everything !

3.2 x 2.5 mm

5 x 3.2 mm

7 x 5 mm


Benefits

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

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

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


Semiconductor Technology Milestones

  • 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
