18QHTF21-10.111-PD

Overview

The 18QHTF21-10.111-PD is a standard crystal oscillator manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a frequency of 10.111 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes a standby or power-down capability. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm.

Feature Summary

• Integrates LVCMOS output logic for digital interface compatibility
• Supports standby mode via power-down control signal
• Utilizes a surface-mount 4-pin no-lead package design

Applications

• General purpose timing clock generation
• Digital signal processing circuits
• Communication equipment synchronization

Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against the target application circuit before procurement. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the 2.0x1.6mm footprint matches the PCB layout constraints to prevent mechanical interference during assembly.

Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a small form factor. The LVCMOS output is suitable for direct interfacing with standard digital logic families. Consider the power-down feature if energy efficiency during idle states is a critical design parameter for the end product.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which focuses on miniature crystal oscillators. The series typically offers various frequencies within a standardized 4-SMD package. The 'PD' suffix indicates the inclusion of a power-down pin for active management of device consumption.

Replacement Considerations

Direct substitutes must match the 10.111 MHz frequency, 1.8V supply, LVCMOS output, and 2.0x1.6mm package. Verify equivalent electrical characteristics such as phase noise and stability before substitution.
