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 cir-

cuit 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 fre-

quency response, making possible a stable 3rd overtone oscillator with only the addition of a crystal element.

FEATURES

^ꢀ3.0 to 3.6V operating supply voltage range

^ꢀ125 to 165MHz recommended operating fre-

quency range

^ꢀf output frequency (oscillator frequency)

^ꢀ8mA output drive capability (V = 3.0V)

^ꢀCMOS output duty level

^ꢀInverter ampliﬁer feedback resistor built-in

^ꢀChip form (CF5005B××)

^ꢀOscillator capacitors C , C built-in

^ꢀOutput three-state function (high impedance in

standby mode, oscillator stops)

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 charac-

teristics and mounting conditions, so the oscillation characteristics of components must be carefully evaluated.
