Global Positioning Systems (GPS)
Crystal Oscillator facilitates tracking of GPS signals.
Press Release Summary:
Packaged as standard 5 x 3.2 mm SMD, Model CFPT-127 TCXO offers frequency stability of ±0.5 ppm over -40 to +85°C temperature range. Miniature, RoHS-compliant unit is designed specifically for GPS equipment, providing DC-coupled clipped sinewave output at standard frequencies of 16.32, 16.8, 19.2, 24.5535, 26.0, and 33.6 MHz. Drawing 2 mA from 3 V supply, Model CFPT-127 is capable of detecting and tracking weak GPS signals.

High-stability, Low-cost 5 x 3.2 TCXO Enhances Tracking of GPS Signals
C-MAC MicroTechnology launches range of miniature, low-cost, RoHS compliant TCXOs offering frequency stability of ±0.5 parts per million over the -40° to +85°C temperature range. Packaged as a standard 5 x 3.2 mm SMD, the new CFPT-127 offers a range of output frequencies between 16.32 and 33.6 MHz.
September, 2006, Durham, NC - C-MAC MicroTechnology has launched a range of miniature, low-cost, RoHS compliant TCXOs (temperature compensated crystal oscillators) offering frequency stability of ±0.5 parts per million over the -40° to +85°C temperature range. Packaged as a standard 5 x 3.2 mm SMD, the new CFPT-127 offers a range of output frequencies between 16.32 and 33.6 MHz.
The CFPT-127 has been designed specifically for GPS equipment, providing a DC-coupled clipped sinewave output at standard frequencies of 16.32, 16.8, 19.2, 24.5535, 26.0 and 33.6 MHz. Drawing just 2 mA (typical) from a 3 V supply, its low power requirement and tiny 5 x 3.2 mm package size make it ideal for use in handheld and portable receivers, while its ±0.5 ppm temperature stability imparts high sensitivity in detecting and tracking weak signals. In this way, a tiny low-cost component enhances both the performance and the battery life of GPS systems.
The CFPT-127 is supplied on standard tape and reel and supports lead-free reflow soldering at 260°C. Typical ageing over the first year is ±1 ppm at 25°C.
"GPS technology is fast moving into the mainstream, not least in mobile handsets and automotive satellite navigation systems," said Mary Carbin, Business Development Manager - Frequency Control Products with C-MAC MicroTechnology. "This means that each system component must be competitive in every respect. Among GPS timing devices, the CFPT-127 represents the best combination of performance enhancing stability, compact design, low price and efficient delivery."
