Oscillators Optimized for Gigabit Ethernet Configurations

Mon, 06/21/2010 - 7:26am
Oscillators Optimized for Gigabit Ethernet ConfigurationsFox Electronics, a leading global supplier of frequency control solutions, recently announced a line of XpressO oscillators explicitly designed to meet the needs of Gigabit Ethernet (GbE) and 10 GbE applications. Each model in the new Application Specific XpressO line is off-the-shelf, pre-configured to precise application-specific requirements in an industry standard 7 x 5 mm package.

The series is the first to combine Fox's patented breakthrough XpressO technology with the specific characteristics required to meet the demanding needs of 3.3-volt (±5% standard) Ethernet-specific applications to ensure the best performance possible without the wait associated with custom products. XpressO technology offers fast delivery of low jitter, small package size and multiple frequency and output options at a low cost. Designed and developed by Fox, XpressO oscillators utilize a family of proprietary application specific integrated circuits (ASICs) with a key focus on noise reduction.

The XO oscillators offer a frequency stability of ±50 ppm, with tighter stabilities available upon request and are available in 125.00 MHz, 156.25 MHz, and 312.50 MHz models. HCMOS, LVPECL, and LVDS outputs are available on the 125.00 MHz and 156.25 MHz models while LVPECL and LVDS outputs are available on the 312.50 MHz model. The XpressO oscillators offer a tri-state enable/disable feature, allowing the user to turn the output on and off. Output enable/disable time is less than 100 nS.
