SM5021 series Crystal Oscillator Module ICs OVERVIEW The SM5021 series are crystal oscillator module ICs fabricated in NPC’s Molybdenum-gate CMOS, that incorporate high-frequency, low current consumption oscillator and output buffer circuits. Highly accurate thin-lm feedback resistors and high-frequency capacitors are built-in, eliminating the need for external components to make a stable 3rd overtone oscillator. FEATURES I I I I I 3rd overtone oscillation Oscillator capacitors CG, CD built-in Inverter amplier feedback resistor built-in (A×, B× series) TTL input level Output drive capability 4mA (VDD = 2.7V) 8mA (VDD = 4.5V) I I I I I Output three-state function Operating supply voltage range 2.7 to 5.5V (A×, K× series) 4.5 to 5.5V (B×, L× series) Oscillator frequency output 6-pin SOT (SM5021××H) Chip form (CF5021××) SERIES CONFIGURATION Operating supply voltage range [V] Chip SM5021AAH SM5021ABH SM5021ACH SM5021ADH SM5021AEH SM5021BAH SM5021BBH SM5021BCH SM5021BDH SM5021KDH SM5021KEH SM5021LDH 2.7 to 5.5 2.7 to 3.6 4.5 to 5.5 2.7 to 5.5 2.7 to 3.6 4.5 to 5.5 22 to 50*3 50 to 70*3 × 4.5 to 5.5 4.5 to 5.5 × 2.7 to 3.6 × 2.7 to 5.5 2.7 to 5.5 4.5 to 5.5 SOT 4.5 to 5.5 Recommended operating frequency range*2 [MHz] 3V 5V operation operation × 22 to 30 30 to 40 40 to 50 50 to 70 22 to 30 30 to 43 43 to 55 55 to 70 × 22 to 30 30 to 43 43 to 55 55 to 70 22 to 70*3 × 22 to 70*3 8 8 15 12 15 8 15 12 8 15 Built-in capacitance [pF] CG CD 1 1 2 3 4 1 1 2 3 3 4 3 6.0 3.3 3.9 2……
