The device supports a supply voltage of 1.8V and includes an enable/disable control function for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm.

Oscillators Feature Summary

• LVCMOS output logic for digital interface compatibility
• Integrated enable/disable pin for power control
• Compact 4-SMD no-lead surface mount package

Oscillators Applications

• Digital signal processing systems requiring precise timing
• Communication equipment utilizing 25.1644 MHz clock signals
• Embedded systems with 1.8V logic level requirements

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the enable/disable pin functionality is utilized correctly to manage power consumption during idle states. Check for RoHS compliance status if environmental regulations apply to your manufacturing process.

Oscillators Selection Notes

Select this component when a stable 25.1644 MHz clock source is required for LVCMOS-compatible circuits. The choice is driven by the need for low-power operation via the enable feature and space constraints necessitating the small 4-SMD footprint. Consider the operating temperature range and stability specifications relative to your application environment.

Oscillators Part Context

This part belongs to the 18QHTF21 series of standard crystal oscillators from Mercury Electronics. The series offers various frequencies within the same compact form factor. The '-OE' suffix typically denotes specific ordering or packaging variations, though functional characteristics remain consistent with the base model specifications provided in official documentation.

Oscillators Replacement Considerations

Direct substitutes must match the 25.1644 MHz frequency, LVCMOS output, 1.8V supply, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility and electrical parameters such as phase noise and jitter before substitution.
