CF5011 series 1.8V Crystal Oscillator Module ICs .. OVERVIEW The CF5011 series are low-voltage crystal oscillator module ICs that operate at 1.8V. The crystal oscillator circuit and output buffer employ a low-voltage CMOS process operating at 1.8V. The crystal oscillator circuit has a built-in thin-film feedback resistor with good temperature characteristics and built-in capacitors with excellent frequency response, making possible a stable 3rd-harmonic oscillator with only the addition of a crystal element. Features 3rd-harmonic oscillation 1.6 to 2.0V operating supply voltage range 30 to 70MHz remended operating frequency range Inverter amplifier feedback resistor built-in Oscillator capacitors CG , CD built-in I I I I I Standby function f O output frequency (oscillator frequency) 8m A output drive capability (VDD = 1.6V) CMOS output duty level Chip form (CF5011×××) SERIES CONFIGURATION Version CF5011ALA CF5011ALB1 CF5011ALC1 CF5011ALD1 CF5011ANA CF5011ANB CF5011ANC CF5011AND 1.
