Pin Configurable/Selectable Oscillators are oscillators that are configurable by the designer, enabling them to be adjusted to specific needs. Their configurability can be in the form of external pin-controlled selection, control of frequency, or adjustment of power consumption. 534BB000505DG, specifically, is a temperature compensated voltage controlled crystal oscillator (VCXO) with run-in-time selector pin. This device ensures good short term stability, tight frequency accuracy and excellent aging performance characteristics.

Application Field: 534BB000505DG is typically used in high-precision, low-jitter, telecom, clock and data communication applications, as well as critical frequency control applications such as Serdes, Radio, Network and computing applications. It offers an ideal solution for an active base VCXO or TCXO application, offering reliability and performance in a low-cost, efficient package.

Working Principle: 534BB000505DG is a VCXO with a pin-programmable, selectable-frequency operation. The frequency range is from 10.00MHz to 75.00MHz. A metal coating transformer on the quartz is used to set the frequency & allow different frequencies to be set by the user-selectable pin activated transformer. A Transcutaneous Inductor is used to regulate the oscillator’s frequency range by switching different portions of the inductive path. The oscillator performs excellent short term stability despite the usage of this frequency-setting system and offers internal temperature compensation as well.

534BB000505DG can also be used as a programmable frequency filter in conjunction with a synthesized generator to adjust the output frequency. It has a resistance-free Drive Pin to operate external circuit signals, that are directly available to the user via the pins connected to the oscillator. It also features low temperature coefficients and boasts quick-start stability (typically within 15 minutes). These features combined with the device\'s low power dissipation, high reliability and wide dynamic range make 534BB000505DG an ideal fit for Pin Configurable/Selectable Oscillators applications.

534BB000505DG is intended for use in a temperature range between 0°C to 70°C and can operate up to a supply voltage of 3.3V. The device requires an external oscillator load of 15pF or higher and its rise/fall/tune times typically range from 5ns to 20ns, respectively. 534BB000505DG is available in a Surface Mount package (SIP4C) with four pins for easy installation that does not require external wiring.
