Crystal Oscillator Model Name NT2520SA Temperature-Compensated Crystal Oscillator with AFC Function (VC-TCXO) NT2520S Series n Main Application For mobile phones, etc. n Features l Supports low power supply voltage. (Supports DC +2.4±0.1 V to +3.4 V±5%.) l Ultra-compact and light with a height, cubic volume, and weight of 0.8 mm max., 0.0035 cm3, and 0.013 g, respectively. l With an AFC (Automatic Frequency Control) function. l Low power consumption. Pb Free 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 NT2520SA Item Standard nominal frequency (MHz) 13 to 26MHz +2.8V DC Power supply voltage 10kΩ//10pF Load 1.5mA max Consumption current 0.8V(P-P) min (DC superimposition *1) Output level ±2.5×10–6 max Frequency / temperature characteristic –30 to +75°C Power supply variation characteristics ±0.2×10–6 max/+2.8V±5% –6 ±0.2×10 max /(10kΩ//10pF)±10% Load variation characteristics Aging ±1.0×10–6 max/year Frequency control characteristics –6 ±9.0×10 to ±15.0×10–6/+1.4V±1V *2 • 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. • If you require a product with a different frequency, power supply voltage, frequency control characteristic, 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. *1. A DC-cut capacitor is not embedded in this crystal oscillator. Connect a DC-cut capacitor (1,000 pF) to the line-out terminal of the oscillator. *2. This is a representative specification. The specifications may change according to the frequency that you request. n Dimensions n List of Ordering Codes mm 2.5±0.2 PAD No. #3 #1 2.0±0.2 #4 #1 Connection VCONT #2 GND #3 OUTPUT #4 VCC #2 Frequency (MHz) Ordering Code 13 NT2520SA-13M-NSA3400B 19.2 NT2520SA-19.2M-NSA3400B 26 NT2520SA-26M-NSA3400B The above frequencies are NDK’ s standard frequencies.
