18QHTF21-27.003375-PD

Oscillators Overview

The 18QHTF21-27.003375-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a fixed frequency of 27.003375 MHz and utilizes LVCMOS output logic. The device requires a supply voltage of 1.8V and features a standby or power-down mode for energy management. It is housed in a compact 4-SMD, no-lead package with dimensions of 2.0mm x 1.6mm.

Oscillators Feature Summary

• Supports low-voltage operation at 1.8V
• Includes standby functionality for power reduction
• Utilizes LVCMOS output interface

Oscillators Applications

• General-purpose clock signal generation
• Embedded system timing references
• Digital circuit 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 to guarantee proper soldering and electrical connection during assembly.

Oscillators Selection Notes

Select this component when a precise 27.003375 MHz reference is required for LVCMOS-compatible digital circuits. Consider the 1.8V operating voltage constraint and the availability of a standby mode for power-sensitive applications. Evaluate the small 2.0x1.6mm form factor against available board space constraints to ensure mechanical compatibility with the target design layout.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series offers various frequencies with standardized LVCMOS outputs. The 'PD' suffix typically indicates the inclusion of a power-down control feature, distinguishing it from standard continuous-operation variants within the same package family.

Oscillators Replacement Considerations

Direct substitutes must match the 27.003375 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Verify pinout compatibility and thermal characteristics. Cross-reference with other manufacturers offering identical electrical parameters and physical dimensions to ensure seamless integration without redesign.
