Procurement Notes

Verify the specific ordering suffix required for your packaging needs, such as tape and reel or cut tape options, when placing orders. Confirm that the supply voltage requirements align with your system design before procurement. Ensure compatibility with the specified operating temperature range for your intended environment. Check for any specific handling instructions related to surface-mount assembly processes.

Selection Notes

Select this component when a precise 32.768 kHz reference is needed for real-time applications. Consider the HCMOS output level compatibility with your target logic family. Evaluate the physical dimensions against your PCB layout constraints. Assess the power consumption characteristics relative to your battery life requirements. Verify that the tri-state feature meets your system's control architecture needs.

Part Context

This oscillator belongs to the standard XO category within Geyer Electronic's frequency control portfolio. It serves as a fundamental timing element for digital systems requiring accurate second-based intervals. The component replaces discrete crystal and load capacitor networks by integrating the resonator and drive circuitry into a single surface-mount package.

Replacement Considerations

Consult official manufacturer substitution lists for direct replacements. Verify pinout compatibility and electrical specifications before swapping components. Ensure that alternative parts meet the same frequency stability and voltage requirements.
