Crystal Oscillator NEW Model Name NT2520SB Temperature-Compensated Crystal Oscillator (TCXO) NT2520S Series (with high-precision GPS supported) n Main Application For mobile terminals with high-precision GPS functions n Features l A crystal oscillator with highly stable frequency / temperature characteristics best suited for GPS. l Supports low power supply voltage. (Supports DC +1.8 V±0.1 V to +3.2 V±0.1 V.) l Ultra-compact and light with a height, cubic volume, and weight of Max. 0.9 mm, 0.004 cm3, and 0.014 g, respectively. Pb Free l Low power consumption. l A surface-mount crystal oscillator. (Reflow soldering is possible.) l Lead-free. Meets the requirements for re-flow profiling using lead-free solder. n Specifications Model Item • Frequency setting conditions 1. Frequencies are set at normal temperatures (+25±2 °C). 2. Frequencies are set with a printed board that has a ground pattern attached to the underside of an oscillator. 3. Connect the #1 terminal of the oscillator to the ground that comes with the oscillator. • If you require a product with a different frequency, power supply voltage, frequency control range, etc. to the standard specifications, please contact us with your enquiries. • Products with the AFC (Automatic Frequency Control) function are available.
