18QHTF21-116.000-PD

Overview

The 18QHTF21-116.000-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 116.000 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features a standby or power-down function to manage energy consumption. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount applications requiring precise timing signals.

Feature Summary

• Supports low-voltage operation with 1.8V supply requirement
• Includes standby mode capability for power management
• Provides LVCMOS output signal compatibility

Applications

• Digital clock signal generation
• Data communication interface timing
• Microprocessor system clocks

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V operating voltage aligns with the system power rails. Ensure the 4-SMD no-lead package footprint matches the PCB layout specifications to guarantee proper soldering and mechanical stability during assembly processes.

Selection Notes

Select this component when a stable 116 MHz reference is required for LVCMOS-compatible digital circuits. Consider the 1.8V supply constraint and the availability of standby functionality for power-sensitive designs. Evaluate the thermal performance and size constraints of the 4-SMD package relative to the available board space and mounting orientation requirements.

Part Context

This part belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronics. The series typically offers various frequency options within a standardized small outline package format. The manufacturer specializes in quartz crystal products, providing frequency control solutions for electronic systems requiring reliable timing sources.

Replacement Considerations

Direct substitutes must match the 116 MHz frequency, LVCMOS output type, 1.8V supply voltage, and 4-SMD no-lead package dimensions. Verify pinout compatibility and electrical characteristics such as phase noise and jitter specifications to ensure functional equivalence in the application.
