Fox Expands Line of Radio Frequency Crystal Oscillators With Addition of New Cost- Effective,Low Voltage rfXOs
Fort Myers, FL, February 2004 - Fox Electronics, America's leading supplier of frequency control products, has expanded its line of radio frequency crystal oscillators (rfXOs) with the addition of two new low voltage series of crystal oscillators. The new 2.5 V RFX250 and RFV250 series of rfXOs feature exceptionally low jitter and phase noise, enabling the full use of the allotted bandwidth in a system, as well as lower bit rate errors in optical data communications. This makes the new rfXOs ideal for use in high performance applications including SONET, ATM, SDH, Gigabit Ethernet, and WAN, as well as for timing reference in optical and data communications systems.
Designers employing Fox's new rfXOs can achieve up to a 40% reduction in costs over other RF crystal oscillators, significantly improving the cost-to-performance ratio of systems using these devices.
The LVE-PECL crystal oscillator (XO) RFX250 and LVE-PECL voltage controlled crystal oscillator (VCXO) RFV250 feature phase jitter of <0.5 pS and a frequency range from 600 MHz to 1.25 GHz, and are housed in an industry-standard 7.5 x 5.0 x 1.5 mm ceramic package. The RFX250 XO has a standard operating temperature of -20°C to 70°C (-4°F to 158°F) with ±20 ppm stability and an extended temperature range of -40°C to 85°C (-40°F to 185°F) with ±25 ppm stability. The RFV250 VCXO offers ±50 ppm APR (Absolute Pull Range) over a standard operating temperature of -40°C to 85°C (-40°F to 185°F). Output symmetry for both series of rfXOs is 45% to 55% at 50% Vdd over the frequency range.
Pricing for a new RFV250 oscillator at 1.25 GHz starts at $35.58 per unit in 1,000 piece quantities. Delivery is stock to 16 weeks ARO.
