Original Press Release:

Low-cost, Pb-free SMD TCVCXOs deliver 0.5 ppm over -40° to +85°C

A miniature, low-cost, lead-free TCVCXO (temperature compensated, voltage controlled crystal oscillator) range offering frequency stability of ±0.5 parts per million over the -40° to +85°C temperature range has been introduced by C-MAC MicroTechnology. Packaged as a standard 7 x 5 mm SMD, the new CFPT-126 is available in a range of frequencies between 10 and 40 MHz for use in GPS, communications, networking and instrumentation applications.

To help equipment manufacturers to comply with new environmental obligations, the CPFT-126 is designed for lead free soldering and compliant with all requirements of the RoHS (Restriction of Hazardous Substances in electrical and electronic equipment) regulations.

With a 3.3 V supply voltage and HCMOS output at nominal frequencies of 10.0, 12.8, 13.0, 16.384, 19.44, 20.0, 26.0, 32.768 and 40.0 MHz, the CFPT-126 is applicable to a range of applications including telecommunications, microwave and satellite communication systems, GPS, Ethernet products, and test and measurement equipment. Its output frequency can be adjusted by more than ±5 ppm through voltage control to calibrate it to nominal after assembly.

The CFPT-126 is supplied on standard tape and reel and supports lead-free reflow soldering at 260°C. Storage temperature range is -55° to +125°C, and typical ageing over the first year is ±1 ppm at 25°C. Components are held in stock for fast delivery.

"Despite their high stability, C-MAC can provide these new TCXOs as off-the-shelf products at off-the-shelf prices," said Mary Carbin, Business Development Manager with C-MAC Frequency Products. "Not that we're expecting them to stay on the shelves for long at the price-performance point we are offering - we envisage a significant mass-market uptake in emerging GPS, comms and instrumentation applications."
