1 / 1 page Crystal Oscillator 1803E_NT2520SB_AFC_e Temperature Compensated Crystal Oscillator with AFC function(VC-TCXO) NT2520SB Smartphone / Mobile phone, Wireless module, and GPS / GNSS module, etc. ■ Main Application ● Supports low power supply voltage. (Supports DC +1.7V to +3.3V. Standard specification : +1.8V and +2.8V) ● Compact and light with a height, cubic volume, and weight of Max. 0.9 mm, 0.004 cm3, and 0.014 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. ● With an AFC (Automatic Frequency Control) function. ■ Features Item Model NT2520SB Nominal Frequency (MHz) 10 to 52 Standard Frequency (MHz) 16.368 16.369 19.2 26 33.6 38.4 52 Supply Voltage [VCC] (V) +1.8, +2.8 Load Impedance 10 kΩ//10 pF Current Consumption (mA) Max. 1.5 Max. 1.7 Max. 2.0 Output Voltage Min. 0.8 V(p-p) (DC Coupling *1) Frequency/Temperature Characteristics Max. ±2.0×10–6 Operating Temperature Range (°C) –30 to +85 Storage Temperature Tange (°C) –40 to +85 Frequency/Voltage Coefficient Max. ±0.2×10–6/VCC±5 % Frequency/Load Coefficient Max. ±0.2×10–6/(10 kΩ//10 pF) ±10 % Long-term Frequency Stability Max. ±1.0×10–6/year Frequency Control Range ±8.0 to ±13.0×10–6/+0.9 V ± 0.8 V (Supply Voltage : +1.8V) ±9.0 to ±15.0×10–6/+1.4 V ± 1.0 V (Supply Voltage : +2.8V) •Frequency setting conditions : Frequencies are set at normal temperatures (+25±2 °C). *1.
