18QHTF21-88.4736-OE

Overview

The 18QHTF21-88.4736-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 88.4736 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes enable/disable control capabilities. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications requiring precise timing signals.

Feature Summary

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

Applications

• General purpose clock signal generation
• Digital system timing references
• Embedded controller clock sources

Procurement Notes

Verify the specific frequency tolerance and operating temperature range against the official datasheet before integration. Confirm that the 1.8V supply voltage aligns with the target circuit design. Ensure the 4-SMD package footprint matches the PCB layout requirements to guarantee proper soldering and mechanical stability during assembly processes.

Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside LVCMOS outputs. The enable/disable feature supports systems needing dynamic power control. Consider the small form factor for space-constrained designs. Validate that the 88.4736 MHz frequency meets the specific timing requirements of the application without additional frequency synthesis.

Part Context

This part belongs to the Mercury Electronics 18QHTF21 series of standard XO oscillators. The series offers various frequencies with consistent 1.8V LVCMOS specifications. Similar models include variants like 18QHTF21-88.000-PD, differing primarily in frequency and ordering suffixes which may indicate package or tolerance variations.

Replacement Considerations

Direct substitutes within the same series include 18QHTF21-88.000-PD, though frequency differences must be accounted for. Verify pinout compatibility and electrical characteristics with alternative suppliers' offerings to ensure functional equivalence in the target application.
