12.94456

Overview

The Geyer Electronic America, Inc. part number 12.94456 is a surface-mount crystal oscillator (XO) designed for standard timing applications. It operates at a fixed frequency of 3.6864 MHz and utilizes CMOS or TTL logic output levels. The device supports a supply voltage of 3.3V and features a tri-state output enable function for power management flexibility. It is housed in a compact 4-SMD, no-lead package suitable for automated assembly processes.

Feature Summary

• Provides stable clock signals via a standard XO architecture
• Features tri-state output enable for system power control
• Compatible with CMOS and TTL logic families

Applications

• Digital circuit timing references
• Microcontroller clock sources
• Communication interface synchronization

Procurement Notes

Verify the specific datasheet version to confirm RoHS compliance status and exact pinout configuration before integration. Ensure that the 3.3V supply requirement aligns with the target system design. Confirm that the 4-SMD package dimensions match the PCB footprint requirements to avoid mechanical interference during assembly.

Selection Notes

Select this component when a precise 3.6864 MHz reference is required for digital systems. The tri-state feature allows for dynamic clock gating, which can reduce power consumption in idle states. Consider the operating temperature range and load capacitance specifications to ensure stability across the intended environmental conditions.

Part Context

This oscillator belongs to Geyer Electronic America's line of surface-mount timing devices. It serves as a replacement for through-hole crystals where space constraints and manufacturing efficiency are priorities. The 4-SMD form factor facilitates high-volume production and reliable solder joint formation compared to traditional leaded packages.

Replacement Considerations

Direct substitutes must match the 3.6864 MHz frequency, 3.3V supply, and 4-SMD package. Verify electrical compatibility regarding drive strength and output logic levels. Cross-reference with other manufacturers offering equivalent XO specifications to ensure availability and performance parity.
