1 / 8 page CF5018 series SEIKO NPC CORPORATION —1 2.5V 3rd Overtone Crystal Oscillator Module ICs OVERVIEW The CF5018 series are crystal oscillator ICs that operate from 2.5V. Devices are available that provide 3rd overtone oscillation in the range 30MHz to 80MHz. They are optimized for 2.5V operation, resulting in stable oscillator startup characteristics and output duty stability. They feature a large reduction in chip surface area compared to existing devices, making possible the construction of small-sized crystal oscillator. FEATURES I 2.25 to 2.75V operating supply voltage range I 30MHz to 80MHz oscillation frequency range (varies with version) I – 40 to 85 °C operating temperature range I Oscillation capacitors CG, CD built-in I Inverter amplifier feedback resistor built-in I Standby function • High impedance in standby mode, oscillator stops I Low standby current • Power-saving pull-up resistor built-in I fO output frequency (oscillation frequency) I 8mA output drive capability (VDD = 2.25V) I CMOS output duty level (1/2VDD) I 50 ± 5% output duty (at 1/2VDD) I 30pF output load I Molybdenum-gate CMOS process I Chip form (CF5018AL ×) SERIES CONFIGURATION ORDERING INFORMATION Version Operating supply voltage range [V] Recommended operating frequency range1 [MHz] 1. The recommended operating frequency is a yardstick value derived from the crystal used for NPC characteristics authentication. However, the oscillator frequency band is not guaranteed. Specifically, the characteristics can vary greatly due to crystal characteristics and mounting condi- tions, so the oscillation characteristics of components must be carefully evaluated. gm ratio Built-in capacitance [pF] Rf [k Ω] CG CD CF5018ALA 2.25 to 2.75 30 to 36 0.25 8 15 4.7 CF5018ALB 36 to 40 0.50 3.5 CF5018ALC 40 to 50 0.75 3.5 CF5018ALD 50 to 60 1.00 3.0 CF5018ALE 60 to 80 1.50 10 3.5 Device Package CF5018AL ×–2 Chip form |
