18QHTF21-114.240-PD

Overview

The 18QHTF21-114.240-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 114.24 MHz and utilizes LVCMOS output logic. The device is designed for 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, suitable for surface-mount applications requiring precise timing signals.

Feature Summary

• Supports low-voltage operation at 1.8V with LVCMOS output compatibility
• Integrates a standby mode to reduce power consumption during idle periods
• Utilizes a leadless SMD package design for efficient board space utilization

Applications

• Digital signal processing systems requiring stable clock sources
• Communication equipment utilizing high-frequency timing references
• Consumer electronics with strict power management requirements

Procurement Notes

Verify the specific ordering suffix and frequency tolerance against project specifications before purchase. Confirm that the 1.8V supply voltage aligns with the target system's power rails. Ensure the 4-SMD no-lead package dimensions fit within the designated footprint on the printed circuit board layout.

Selection Notes

Select this component when a 114.24 MHz clock signal is required with low-power standby capabilities. Consider the LVCMOS interface for direct compatibility with standard digital logic families. Evaluate the thermal performance and operating temperature range to ensure reliability under expected environmental conditions.

Part Context

This part belongs to the 18QHTF series of standard oscillators from Mercury Electronics. The series typically offers various frequencies and voltage options. The PD suffix indicates the inclusion of a power-down feature, distinguishing it from continuous-operation variants within the same product family.

Replacement Considerations

Direct substitutes must match the 114.24 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify pinout compatibility and electrical characteristics before swapping. Consult manufacturer cross-reference lists for approved equivalent components.
