18QHTF21-114.560-OE

Overview

The 18QHTF21-114.560-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 114.56 MHz and utilizes LVCMOS output logic levels. The component is designed for low-voltage applications, functioning with a supply voltage of 1.8V. It features an enable/disable control function to manage power consumption. The device is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm, suitable for surface-mount assembly on printed circuit boards.

Feature Summary

• LVCMOS output interface for digital signal compatibility
• Integrated enable/disable functionality for power management
• Compact 4-SMD no-lead surface mount package design

Applications

• Digital clock distribution systems
• Data communication interfaces requiring precise timing
• Embedded systems with low-voltage logic requirements

Procurement Notes

Verify the specific suffix 'OE' against the manufacturer's current datasheet to confirm availability and exact electrical tolerances. Ensure the 1.8V supply voltage aligns with the target system's power rails. Confirm that the 4-SMD no-lead footprint matches the PCB land pattern specifications before finalizing procurement orders.

Selection Notes

Select this component when a 114.56 MHz reference signal is required within a 1.8V logic environment. The LVCMOS output is appropriate for direct interfacing with standard digital inputs without additional level shifting. Consider the small form factor for space-constrained designs where surface-mount technology is preferred over through-hole alternatives.

Part Context

This part belongs to the QHTF series of standard crystal oscillators from Mercury Electronics. The series offers various frequencies and voltage options. The 18 prefix indicates the 1.8V operating voltage, while the 21 likely denotes the package type or series variant. This specific model provides a high-frequency solution for timing-critical applications in consumer and industrial electronics.

Replacement Considerations

The 18QHTF21-114.560-PD is a documented substitute variant from the same manufacturer. Verify pinout compatibility and electrical parameter equivalence before substitution. Cross-reference with other 1.8V LVCMOS oscillators if original stock is unavailable.
