Components: Ultra-Small And Thin Low-Noise TCXO: A Good Mix For Mobile Phones

Measuring a mere 3.2 by 2.5 by 1.2 mm high, the NT3225 series surface-mount temperature-compensated crystal oscillator (TCXO) is well suited for mobile phones. Standard frequencies include 12.6, 13.0, 14.4, 19.2, 19.68, and 26 MHz. Features include a low phase noise of −137 dBc/Hz with a 1-kHz offset, frequency stability of ±2.5 ppm maximum over the operating-temperature range of −30°C to 85°C, and a 0.8-V p-p output voltage. It operates from 2.4 V dc ±0.1 V at 1.5 mA with a 10-kΩ load at 10 pF. Audio frequency control (AFC) characteristics are ±9 to ±15 ppm at 1.5 V, ±1 V. Aging characteristics are ±1 ppm/year. Price in 10,000-unit lots is $2.95 each (12.6-MHz unit). Delivery is within eight to 10 weeks.
