Crystal Clock Oscillator NZ2520S Series ■ Model name NZ2520SB Overall frequency tolerance of ±30 x 10–6. ■ Application ● For compact mobile information equipment, such as DVC, DSC, notebook PC, and PDA ■ Features Absolute maximum rating Supply voltage (VCC) –0.5 to +4.0 V Storage temperature range –55 to +125 °C ● Compact and light. Dimensions : 2.5 x 2.0 x 0.9 mm, weight : 0.02 g. ● This crystal clock oscillator can support low frequencies (from 1.5 MHz); an achievement not easy for other crystal oscillators of the same size to equal. ● Automatic mounting by taping and IR reflow (lead-free) are possible. ● Lead-free. ■ Specifications Model Item NZ2520SB Output level CMOS Nominal frequency range *1 (MHz) 1.5 ≤ F < 10 10 ≤ F < 20 20 ≤ F < 30 30 ≤ F < 40 40 ≤ F < 50 50 ≤ F < 60 60 ≤ F < 70 70 ≤ F ≤ 80 Operating temperature range *2 (°C) Overall frequency tolerance Current consumption max During operation (×10 ) ±30 +1.8 V, 25 °C 2.5 3.5 4.0 4.5 5.0 5.5 6.0 6.5 +2.5 V, 25 °C 3.0 4.0 4.5 5.0 5.5 6.0 6.5 7.0 3.5 4.5 5.0 5.5 6.0 6.5 7.5 8.5 3.5 4.5 5.0 5.5 6.0 7.0 8.0 9.0 +3.0 V, 25 °C (mA) +3.3 V, 25 °C During standby –10 to +70 –6 (μA) 10 VOL max/VOH min +1.8 V to +3.3 V, 25 °C (V) 0.1 VCC/0.9 VCC Tr max/Tf max (ns) 5/5 Symmetry min. to max.
