18QHTF21-118.750-PD

Oscillators Overview

The 18QHTF21-118.750-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 118.75 MHz and utilizes LVCMOS output logic levels. The device supports a supply voltage of 1.8V and includes a standby or power-down function for energy management. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications requiring precise timing signals.

Oscillators Feature Summary

• Supports low-voltage operation with 1.8V supply
• Integrates standby mode for power reduction
• Provides LVCMOS compatible digital output

Oscillators Applications

• Digital signal processing systems
• Communication equipment clocking
• Embedded system timing references

Oscillators Procurement Notes

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

Oscillators Selection Notes

Select this component when a stable 118.75 MHz reference is required for LVCMOS interfaces. Consider the 1.8V operating voltage constraint and the availability of the standby feature for power-sensitive designs. Evaluate the thermal performance and size constraints of the 4-SMD package relative to other available oscillator options.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series typically offers various frequencies within the same form factor. The 'PD' suffix likely indicates specific packaging or handling characteristics, while the numeric value denotes the exact operating frequency.

Oscillators Replacement Considerations

Direct substitutes must match the 118.75 MHz frequency, LVCMOS output, and 1.8V supply voltage. Verify pin compatibility for the 4-SMD no-lead package. Check datasheets for equivalent standby functionality and temperature range specifications to ensure seamless integration.
