18QHTF21-10.695-PD

Overview

The 18QHTF21-10.695-PD is a crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 10.695 MHz and utilizes LVCMOS output logic levels. The device functions with a supply voltage of 1.8V and includes a standby or power-down control feature. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm.

Feature Summary

• Supports low-voltage operation at 1.8V
• Integrates standby mode for power management
• Provides standard LVCMOS signal output

Applications

• General-purpose clock generation
• Embedded system timing references
• Portable electronic devices requiring low power consumption

Procurement Notes

Verify the specific part number against official manufacturer documentation to ensure compatibility with design requirements. Confirm that the 1.8V supply voltage aligns with the target circuit's power rails. Ensure the 4-SMD no-lead package footprint matches the PCB layout specifications before finalizing procurement decisions.

Selection Notes

Select this component when a precise 10.695 MHz reference is required within space-constrained designs. The choice depends on the necessity for LVCMOS interface compatibility and the availability of a 1.8V power supply. Consider the physical size constraints imposed by the 2.0x1.6 mm package dimensions during the initial hardware architecture phase.

Part Context

This model belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series typically offers various frequency options within a standardized small outline package format. These components are designed for applications demanding reliable timing signals in modern electronic assemblies.

Replacement Considerations

Direct substitutes must match the 10.695 MHz frequency, 1.8V operating voltage, LVCMOS output type, and 4-SMD no-lead package dimensions. Verify pinout compatibility and thermal characteristics before integrating alternative sources into existing designs.
