OCXO High Stability Oscillator: OX–208

OX-208

The OX-208 is the latest addition to our precision OCXO high stability oscillator family. In a 25.4 x 25.4 mm footprint, this OCXO offers +/-0.8ppb stability over the Industrial Temperature range, while also offering impressive phase noise performance over the frequency range of 5 MHz to 20 MHz. Features include frequency range: 5 to 20 MHz, temp stability: +/-0.4ppb over 0 to 70oC, temp stability: +/-0.8ppb over -40 to 85oC, package: 25.4 x 25.4 x 12.7 mm, aging: 0.15ppb/day and phase noise: -155dBc/Hz@10kHz offset.

Temperature Compensated Crystal Oscillator: VT-706

VT-706Vectron’s VT-706 Temperature Compensated Crystal Oscillator (TCXO) in an industry standard four pin 7.0 x 5.0 mm package. Tight stabilities as low as +/-50 ppb can be achieved in this standard package, to support both legacy systems for backwards compatibility and newer designs where footprint compatibility with other precision oscillators remains a requirement.

Voltage Controlled Crystal Oscillator: VX-706

VX-706The VX–706 is a new discrete VCXO in a 5 x 7 mm footprint with improved phase noise and jitter performance previously only available in a 9 x 14 mm package (VX–501). As board layouts become increasingly dense, VCXOs must meet performance specifications and deliver it in smaller package sizes. The new VX–706 supports this progression with improved phase noise performance.

Oven Controlled Crystal Oscillator: OX-070

OX-070The OX–070 is a high stability ovenized crystal oscillator in a miniature atomic clock compatible footprint, capable of aging rates of 0.06 ppb/day and temperature stabilities of 1ppb over the industrial temperature range. Driven by an SC–cut crystal, the OX–070 has twice the temperature range, similar aging and temperature performance of the miniature atomic clocks. It also has better Allan Deviation and phase noise than commercially available miniature atomic clocks, at a tenth of the cost.

Oven Controlled Coefficient Corrected Oscillator: MD-223

MD-223The MD−223 OCXO is offered in a 22 x 25 mm footprint and capable of unprecedented stability for an oscillator of this cost, size and power consumption. The I²C interface provides customers control of the oscillator with digital tuning for further correction and stability improvement during holdover. This product is ideal for base stations, test and measurement and synthesizer applications, where performance can be improved with an existing package footprint.
