C-MAC MicroTechnology has launched a range of miniature, low-cost, RoHS-compliant, temperature-compensated crystal oscillators (TCXOs) offering frequency stability of ±0.5 parts per million (ppm) over the –40°C to +85°C temperature range. Packaged as a standard 5 mm x 3.2 mm SMD, the new CFPT-127 offers a range of output frequencies between 16.32 MHz and 33.6 MHz. It has been designed specifically for GPS equipment, providing a DC-coupled clipped sinewave output at standard frequencies of 16.32 MHz, 16.8 MHz, 19.2 MHz, 24.5535 MHz, 26.0 MHz and 33.6 MHz. Drawing just 2 mA (typical) from a 3 V supply, its low power requirement and tiny 5 mm x 3.2 mm package size make it suitable for use in handheld and portable receivers, while its ±0.5 ppm temperature stability imparts high sensitivity in detecting and tracking weak signals.
