CF5005B

CF5005B series High-frequency Crystal Oscillator Module ICs OVERVIEW The CF5005B series are high-frequency crystal oscillator module ICs. They are comprised of an oscillator circuit and output buffer optimized for operation at 125 to 165MHz. 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 overtone oscillator with only the addition of a crystal element. FEATURES I I I I I 3.0 to 3.6V operating supply voltage range 125 to 165MHz 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, oscillator stops) I I I I fO output frequency (oscillator frequency) 8mA output drive capability (VDD = 3.0V) CMOS output duty level Chip form (CF5005B××) SERIES CONFIGURATION Version CF5005BLA CF5005BLB Recommended operating frequency range1 [MHz] 125 to 150 140 to 165 Built-in capacitance [pF] gm ratio CG 1.0 1.0 1 1 CD 6 3 Rf [kΩ] 2.2 2.2 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, when used at high frequencies, the characteristics can vary greatly due to crystal characteristics and mounting conditions, so the oscillation characteristics of components must be carefully evaluated.
