| Crystal Oscillator Model Name NT2520SA n Main Application NEW Temperature-Compensated Crystal Oscillator (TCXO) NT2520S Series (with high-precision GPS supported) 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 +2.40.1 V to +3.20.1 V.) 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 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. Pb Free n Specifications Model Item Standard nominal frequency (MHz) Power supply voltage Load Consumption current Output level Frequency / temperature characteristic Power supply variation characteristics Load variation characteristics Aging NT2520SA 13 to 27.456MHz +2.8V DC 10k//10pF 1.5mA max 0.8V(P-P) min (DC superimposition *1) 0.5x10-6 max -30 to +85C 0.2x10-6 max/+2.8V5% 0.2x10 max /(10k//10pF)10% 1.0x10-6 max/year -6 * Frequency setting conditions 1. Frequencies are set at normal temperatures (+252C). 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 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. n Dimensions mm 2.50.2 #4 #3 2.00.2 n List of Ordering Codes Frequency (MHz) 13 16.368 16.369 16.8 19.2 24.5535 Reference land pattern Ordering Code NT2520SA-13M-NSA3410A NT2520SA-16.368M-NSA3410A NT2520SA-16.369M-NSA3410A NT2520SA-16.8M-NSA3410A NT2520SA-19.2M-NSA3410A NT2520SA-24.5535M-NSA3410A NT2520SA-26M-NSA3410A NT2520SA-27.456M-NSA3410A PAD No. #1 #2 #3 Connection (GND)*2 GND OUTPUT VCC #1 #2 #4 26 27.456 1.450.2 #1 (0.2x0.2) #2 0.70.1 2.1 0.375 0.375 0.275 0.9 The above frequencies are NDK' s standard frequencies.
