18QHTF21-114.500-PD

Overview

The 18QHTF21-114.500-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 114.500 MHz and utilizes LVCMOS output logic levels. The device is designed for low-voltage applications, functioning with a supply voltage of 1.8V. It features a standby or power-down capability to manage energy consumption when not in active use. The component is housed in a compact 4-SMD, No Lead package, suitable for surface-mount assembly on printed circuit boards.

Feature Summary

• Supports LVCMOS output signal compatibility
• Includes standby and power-down functionality
• Operates on a 1.8V supply voltage

Applications

• General-purpose clock signal generation
• Digital system timing references
• Embedded electronics requiring low-voltage oscillators

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your design specifications before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD no-lead package dimensions fit within your PCB layout constraints. Cross-reference the manufacturer datasheet for detailed electrical characteristics and reliability data to ensure compliance with your application standards.

Selection Notes

Select this component when a precise 114.500 MHz clock source is required for digital circuits. The LVCMOS interface ensures compatibility with standard logic families operating at 1.8V. Consider the power-down feature if energy efficiency during idle states is a priority. The small form factor makes it suitable for space-constrained designs. Verify that the operating temperature range meets your environmental requirements.

Part Context

This part belongs to the 18QHTF21 series of standard crystal oscillators from Mercury Electronics. The series offers various frequencies and voltage options. The 'PD' suffix typically indicates the inclusion of a power-down pin or function. These oscillators are designed for general electronic applications requiring stable clock signals. The manufacturer provides these components in surface-mount packages for automated assembly processes.

Replacement Considerations

Direct replacements must match the 114.500 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify equivalent performance metrics such as phase noise and stability if available in official documentation. Consult manufacturer cross-reference lists for confirmed substitutes.
