SMD crystal oscillators deliver 0,5 ppm

10 August 2005 Telecoms, Datacoms, Wireless, IoT

A miniature, low-cost, lead-free TCVCXO (temperature compensated, voltage controlled crystal oscillator) range offering a 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 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. Its output frequency can be adjusted by more than ±5 ppm through voltage control to calibrate it to nominal after assembly.

The CPFT-126 is lead (Pb) free compliant and typical ageing over the first year is ±1 ppm at 25°C.
