18QHTF21-13.000-OE

Overview

The 18QHTF21-13.000-OE is a standard crystal oscillator manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a frequency of 13.000 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and features 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. The component is designed for surface-mount applications and offers reliable timing performance within its specified operating temperature range.

Feature Summary

• Integrates LVCMOS output logic for direct digital interface compatibility
• Includes hardware enable/disable pin for active power state control
• Utilizes a low-profile 4-SMD no-lead surface mount package

Applications

• Embedded system clock generation
• Digital signal processing timing references
• Communication interface synchronization

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the PCB footprint matches the 2.0x1.6mm SMD package dimensions to prevent assembly issues. Check for RoHS compliance status if required by environmental regulations.

Selection Notes

Select this model when a precise 13MHz reference is needed with low voltage operation. The integrated enable feature makes it suitable for battery-powered devices requiring power conservation. Consider the small form factor for space-constrained designs. Verify that the LVCMOS output swing is compatible with the receiving logic levels of the connected microcontroller or FPGA.

Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series typically includes various frequencies and voltage options, such as 1.8V and 3.3V variants. The suffix -OE indicates the presence of an output enable function. This specific model provides a fixed 13MHz output, distinguishing it from programmable or tunable alternatives in the broader product line.

Replacement Considerations

Direct replacements must match the 13MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Cross-reference with other manufacturers offering equivalent pin-compatible solutions. Verify that any substitute maintains the same enable/disable functionality and electrical characteristics to ensure circuit compatibility.
