High performance, low cost

In the competitive telecom, wireless and data communications markets, companies are constantly seeking to improve technical performance and reliability, while reducing costs. To help them meet these sometimes conflicting constraints, Aspen Electronics has announced a new range of temperature compensated crystal oscillators (TCXOs) from Vectron International.

The C2260 series of TCXOs are designed to provide improved phase noise performance, yet are contained in a compact 5 by 7 module.

The company states they are also offered at a highly competitive price. Vectron is utilising a new generation of TCXO integrated circuit design, which is said to stabilise frequency from 6.4MHz to 32MHz (over -30 to 85C) to better than 0.28ppm.

The devices are encapsulated using FR4 base technology. The primary benefit is that the modules will have the same coefficient of expansion as the customers printed circuit board, thus minimising the possibility of failure due to solder joint fatigue.

A second advantage of using FR4, rather than ceramic, is greater flexibility during the design and layout of the oscillator circuit, particularly when optimising pin-outs
for better phase-noise performance figures.
The company states this previously required 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 telecom, wireless and data communications applications, C2260 Series devices are compliant to GR1244-Core and GR253-Core standards. Samples of 12.8MHz and 20MHz versions, designed for the two most important SONET/SDH IC solutions from Semtech and Zarlink, are already available from stock.
