Transcription

1 XO Module IC with Built-in Varicap OVERVIEW The 575 series are miniature XO ICs that provide a wide frequency pulling range, even when using miniature crystal units for which a wide pulling range is difficult to provide. They employ a recently developed varicap diode fabrication process that provides a wide frequency pulling range and good linearity without any external components. Also, they employ a regulated voltage drive oscillator circuit that significantly reduces current consumption, crystal current, and oscillation characteristics supply voltage dependency. The 575 series are ideal for miniature, wide pulling range, low power consumption, XO modules.
