Overview
The Geyer Electronic America, Inc. 12.90333 is a standard crystal oscillator (XO) designed for surface-mount applications. It operates at a nominal frequency of 40 MHz and features an enable/disable control function. The component utilizes a 4-SMD, no-lead package with a maximum seated height of 0.80 mm. It offers a frequency stability of ±50 ppm and functions within an operating temperature range of -40°C to +85°C.
Feature Summary
- Integrated enable/disable functionality for power management
- Ultra-miniature surface-mount construction
- Wide industrial temperature operation capability
Applications
- Digital signal processing timing references
- Communication equipment clock sources
- Embedded system microcontroller interfaces
Procurement Notes
Verify the specific manufacturer part number against official datasheets to ensure compatibility with design requirements. Confirm that the enable/disable pin configuration matches the target circuit logic levels. Check lead times as manufacturing schedules may vary. Ensure the selected package variant meets board space constraints regarding the 0.80 mm maximum height.
Selection Notes
Select this component when a precise 40 MHz reference is required in a compact form factor. Consider the ±50 ppm stability specification against system jitter tolerance requirements. Evaluate the enable/disable feature necessity for power-sensitive designs. Verify that the SMD footprint aligns with existing PCB layout guidelines and assembly capabilities.
Part Context
This oscillator belongs to Geyer Electronic's line of quartz-based timing solutions. It complements other models like the 12.90344 by offering different frequency options within similar packaging constraints. The product series emphasizes reliability and miniaturization for modern electronic assemblies requiring stable clock signals.
Replacement Considerations
Cross-reference with other 40 MHz XO components from Geyer or compatible manufacturers ensuring identical package dimensions and electrical specifications. Verify pinout compatibility if substituting with devices lacking enable pins.
