The 534BB000489DGR is a type of pin configurable/selectable oscillator, designed and manufactured by Epson. Typically used in embedded applications, the 534BB000489DGR oscillator is an integrated solution that offers superior accuracy, performance and stability in a small form factor. It is a perfect choice for space-constrained applications that require high frequency, while maintaining good reliability.

The 534BB000489DGR is a unique pin-configurable oscillator that allows users to select different frequency over a wide range without the hassle of manual component swapping. The oscillator is packaged in a tiny 3 mm x 3.2 mm plastic SMD package and typically operates from a 2.5 V to 3.3 V supply. This device integrates two blocks, the oscillator and a programmable frequency selector. It supports a wide range of frequencies from 150 kHz up to 170 MHz, which can be configured using two external control pins by using an external programming voltage.

The working principle of the 534BB000489DGR oscillator is based on the use of on-chip quartz crystal resonator and temperature compensated voltage controlled crystal oscillator (VCXO). The VCXO is digitally controlled by programming the frequency divider with externally programmed logic levels at two control pins. This effectively controls the frequency of oscillation to desired values, as well as allowing changes to be made quickly and easily.

The accuracy of the 534BB000489DGR oscillator is specified to ±25 ppm over industrial temperature range (−40 °C to +85 °C), making it perfect for applications which require superior timekeeping accuracy., while the ultra low power consumption (less than 10 μA) makes it highly efficient. The 534BB000489DGR is designed with maximum ESD protection in order to ensure reliable operation in industrial applications. Moreover, the operating temperature of the oscillator is specified from −40 °C to +85 °C.

In conclusion, the 534BB000489DGR is a pin-selectable oscillator with excellent performance and accuracy, low power consumption, and superior ESD protection. Its wide frequency range and small form factor make it an ideal choice for space-constrained applications requiring frequency tuning, while its reliability and accuracy makes it perfect for time-critical machine operations.
