TCXOs improve phase noise performance
Compact temperature compensated crystal oscillators provide improved phase noise performance at highly competitive prices.
In the highly competitive telecomms, wireless and datacommunications markets, designers are constantly seeking to improve technical performance and reliability, while reducing costs To help them meet these sometimes conflicting constraints, Aspen Electronics has announced the latest range of temperature compensated crystal oscillators (TCXOs) from Vectron International

The CNT-90 is a new tool for measurement, analysis and calibration of frequency, time interval or phase, whether in test systems, on the R and D bench, in the calibration lab or in the field.
Budget price for general-purpose spectrum analyser
The GW Instek GSP-827 general-purpose spectrum analyser is available from Aspen Electronics.
The C2260 series of TCXOs are designed to provide improved phase noise performance, yet are contained in a compact 5 x 7 x 3mm module, and offered at a highly competitive price.
A new generation of TCXO integrated circuit design can stabilise frequency from 6.4 up to 32MHz, over a wide temperature range of -30 to +85C, to better than 0.28ppm.
The devices are encapsulated using well-proven FR4 base technology.
The primary benefit is that the modules will have the same coefficient of expansion as the customer's printed circuit board, thereby minimising the possibility of failure due to solder joint fatigue.
A second advantage of using FR4 materials in place of ceramic is greater flexibility of design and layout of the oscillator circuit, particularly with respect to optimising the pinouts for better phase-noise performance figures.
This has only been achievable before using large, expensive, discrete solutions.
A "wide pull" version of the C2260 family will provide a pull range of +/-40ppm and more.
Ideal for use in a wide range of telecomms, wireless and datacommunications applications, the C2260 Series devices are fully compliant with GR1244-Core and GR253-Core standards.
Samples of 12.8 and 20MHz versions, designed for the two most important Sonet/SDH IC solutions from Semtech and Zarlink, are already available from stock, and mass market sampling of other versions is underway.
