Crystal Oscillator Model Name NT2520SA Temperature-Compensated Crystal Oscillator (TCXO) NT2520S Series (with high-precision GPS supported) ■ Main Application For mobile terminals with high-precision GPS functions ■ Features ● A crystal oscillator with highly stable frequency / temperature characteristics best suited for GPS. ● Supports low power supply voltage. (Supports DC +1.8 V±0.1 V to +3.2 V±0.1 V.) ● Ultra-compact and light with a height, cubic volume, and weight of Max. 0.8 mm, 0.035 cm3, and 0.013 g, respectively. ● Low power consumption. ● A surface-mount crystal oscillator. (Reflow soldering is possible.) ● Lead-free. Meets the requirements for re-flow profiling using lead-free solder. ■ Specifications Model Item Nominal frequency range (MHz) •Frequency setting conditions 1. Frequencies are set at normal temperatures (+25±2 °C). 2. 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. If you require such a product, please contact us.
