18QHTF21-57.373667-OE

Overview

The 18QHTF21-57.373667-OE is a standard crystal oscillator manufactured by Mercury Electronic Ind., Co., Ltd. It operates at a fixed frequency of 57.373667 MHz and utilizes LVCMOS output logic. The device functions on a 1.8V supply voltage and includes an enable/disable control feature for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm.

Feature Summary

• Integrates LVCMOS output logic for direct digital interface compatibility
• Features an enable/disable pin to manage power consumption states
• Utilizes a leadless surface-mount package for automated assembly

Applications

• Digital signal processing circuits requiring precise clock timing
• Communication systems utilizing standard logic interfaces
• Embedded controller boards with low-voltage power constraints

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure the correct packaging configuration and tolerance specifications are selected. Confirm that the 1.8V supply requirement aligns with the target system design before finalizing procurement orders.

Selection Notes

Select this component when a fixed frequency near 57.37 MHz is required with low-voltage operation. Ensure the host circuit supports LVCMOS levels and that the physical footprint matches the 2.0x1.6mm land pattern. Consider thermal performance within the specified operating temperature range during layout.

Part Context

This part belongs to the Mercury Electronics 18QHTF series of standard XO oscillators. The series provides various frequencies and voltage options in a small form factor. The -OE suffix typically denotes a specific packaging or tape-and-reel configuration distinct from other variants like -PD.

Replacement Considerations

Direct substitutes include the 18QHTF21-57.373667-PD from the same manufacturer, which shares identical electrical characteristics but may differ in packaging format. Verify pinout compatibility and reflow soldering profiles before substituting.
