18QHTF21-116.666-PD

Overview

The 18QHTF21-116.666-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 116.666 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
• Includes standby mode for power management
• Utilizes LVCMOS output interface

Applications

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

Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against your circuit design before procurement. Confirm that the 4-SMD no-lead package dimensions align with your PCB footprint. Ensure the 1.8V supply rail stability meets the oscillator's specifications to maintain frequency accuracy during operation.

Selection Notes

Select this component when a 116.666 MHz reference is required with low power consumption capabilities. The LVCMOS output ensures compatibility with standard digital logic families. Consider the standby feature if power efficiency is critical. Verify that the 1.8V supply voltage matches your system architecture before finalizing the selection.

Part Context

This part belongs to the Mercury Electronics 18QHTF21 series of surface-mount oscillators. The series offers various frequencies with consistent packaging and electrical characteristics. The 'PD' suffix indicates the inclusion of a power-down capability, distinguishing it from standard continuous-operation variants within the same family.

Replacement Considerations

Direct replacements must match the 116.666 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify pinout compatibility and thermal performance. Cross-reference with other manufacturers offering similar XO specifications to ensure functional equivalence.
