18QHTF21-115.000-PD

Overview

The 18QHTF21-115.000-PD is a crystal oscillator (XO) manufactured by Mercury Electronic Ind., Co., Ltd. It operates at a frequency of 115.0 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features a power-down function via standby mode. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm.

Feature Summary

• Supports low-voltage operation at 1.8V
• Includes power-down capability for energy management
• Utilizes LVCMOS output interface

Applications

• General clock signal generation
• Embedded system timing references
• Compact electronic devices requiring small form factors

Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required voltage levels and output types. Confirm that the 4-SMD no-lead package aligns with PCB footprint requirements. Check manufacturer documentation for detailed electrical specifications and thermal handling guidelines before integration.

Selection Notes

Select this component when a precise 115.0 MHz clock source is required within space-constrained designs. Ensure the system supports 1.8V logic levels. Consider the power-down feature if dynamic power management is necessary for the application environment.

Part Context

This model belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz crystal and oscillator products. The series is characterized by small footprints and standard output logic options, catering to modern electronics manufacturing needs.

Replacement Considerations

Direct substitutes must match the 115.0 MHz frequency, 1.8V supply, LVCMOS output, and 2.0x1.6mm package dimensions. Verify pinout compatibility and electrical characteristics against original datasheets.
