Low-voltage operation for RF crystal
oscillators
Fox Electronics has expanded its line of radio frequency crystal oscillators (rfXOs) with the addition of two new low-voltage series of crystal oscillators.
Fox Electronics has expanded its line of radio frequency crystal oscillators (rfXOs) with the addition of two new low-voltage series of crystal oscillators The new 2.5V 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 bitrate errors in optical datacommunications

Oscillators run faster and are more stable
Fox Electronics has extended the frequency range and stability options of its popular F4100 Series crystal oscillators to 170MHz with stabilities as tight as +50ppm (F4105) for all conditions.
Ultra-low profile for RTC crystal
Fox Electronics has a miniature watch crystal that measures just 7.0 x 1.5mm with an extremely low profile of 1.4mm.
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 datacommunications 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 better than 0.5ps and a frequency range from 600MHz to 1.25GHz, and are housed in an industry-standard 7.5 x 5.0 x 1.5mm ceramic package.
The RFX250 XO has a standard operating temperature of -20 to +70C with +/-20ppm stability and an extended temperature range of -40 to +85C with +/-25ppm stability.
The RFV250 VCXO offers +/-50ppm APR (absolute pull range) over a standard operating temperature of -40 to +85C.
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 1.25GHz starts at $35.58 per unit in 1000-piece quantities.
Delivery is stock to 16 weeks ARO.
