CF5012

CF5012 series Low-current Consumption Crystal Oscillator Module ICs www.datasheet4u.com OVERVIEW The CF5012 series are low-current consumption 3rd-harmonic crystal oscillator module ICs. Internal circuit optimization means these devices have reduced current consumption in comparison with our existing 3rd-harmonic oscillator devices. The crystal oscillator circuit has a built-in thin-film feedback resistor with good temperature characteristics and built-in capacitors with excellent frequency response, resulting in a stable 3rdorder overtone oscillator with only the connection of a crystal element. FEATURES I I I I I I 3rd-harmonic oscillation 2.7 to 3.6V operating supply voltage range 30 to 45MHz recommended operating frequency range Inverter amplifier feedback resistor built-in Oscillator capacitors CG , CD built-in Output three-state function (high impedance in standby mode) I I I I I fO output frequency (oscillator frequency) 8mA output drive capability (VDD = 2.7V) 6.5mA (typ) low current consumption (VDD = 3V, CL = 15pF, f = 40MHz) CMOS output duty level Chip form (CF5012×××) SERIES CONFIGURATION Version CF5012ANB Recommended operating frequency [MHz] 30 to 45 Built-in capacitance [pF] gm ratio CG 1.0 8 CD 15 Rf [kΩ] 3.1 Note: Recommended operating frequency is not the guaranteed value but is measured using NPC’s standard crystal.
