18QHTF21-27.002-PD

Oscillators Overview

The 18QHTF21-27.002-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 27.002 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 reduce consumption. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm.

Oscillators Feature Summary

• Supports low-voltage operation at 1.8V
• Includes standby and power-down functionality
• Utilizes LVCMOS output logic for digital interfacing

Oscillators Applications

• General clock signal generation
• Digital circuit timing references
• Embedded system synchronization

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your design specifications before procurement. Confirm that the 1.8V supply rail is stable and within the operational limits defined in the official datasheet. Ensure the PCB footprint matches the 4-SMD No Lead package dimensions precisely to avoid assembly issues.

Oscillators Selection Notes

Select this component when a small form factor is required alongside low-power consumption capabilities. The LVCMOS interface is suitable for standard digital logic families. Consider the operating temperature range and stability requirements relative to the application environment to ensure reliable performance over the product's lifecycle.

Oscillators Part Context

This part belongs to the 18QHTF series of surface-mount oscillators from Mercury Electronics. The series is characterized by its small physical footprint and compatibility with automated pick-and-place assembly processes. The 'PD' suffix typically indicates the inclusion of a power-down control feature, distinguishing it from standard continuous-operation variants within the same family.

Oscillators Replacement Considerations

Direct substitutes must match the 27.002 MHz frequency, 1.8V supply, LVCMOS output, and 2.0x1.6mm package. Verify pinout compatibility and electrical characteristics such as phase noise and jitter against the original specification to ensure functional equivalence in the target circuit.
