18QHTF21-14.138-PD

Oscillators Overview

The 18QHTF21-14.138-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a frequency of 14.138 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. 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
• Features LVCMOS output logic compatibility
• Includes standby and power-down functionality

Oscillators Applications

• Digital signal processing circuits
• Communication equipment timing
• Embedded system clock generation

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply voltage aligns with the system's power rails. Ensure the 4-SMD no-lead package footprint matches the PCB layout specifications to guarantee proper soldering and mechanical stability during assembly.

Oscillators Selection Notes

Select this component when a precise 14.138 MHz reference is required for LVCMOS-compatible digital interfaces. The choice is driven by the need for a low-profile surface-mount solution with integrated power management capabilities. Consider the operating temperature range and stability requirements relative to the application environment to ensure long-term reliability.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series is characterized by small form factors suitable for space-constrained designs. The 'PD' suffix indicates the inclusion of power-down control features, distinguishing it from standard continuous-operation variants within the same product line.

Oscillators Replacement Considerations

Direct substitutes must match the 14.138 MHz frequency, 1.8V supply, LVCMOS output, and 2.0x1.6mm package. Verify pinout compatibility and electrical characteristics such as phase noise and jitter before swapping components to maintain system performance integrity.
