18QHTF21-10.024-PD

Overview

The 18QHTF21-10.024-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd, operating at a frequency of 10.024 MHz. It utilizes LVCMOS output logic and functions with a supply voltage of 1.8V. The device features a power-down capability for 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 functionality for energy efficiency
• Provides LVCMOS output signal compatibility

Applications

• General clock generation for digital circuits
• Embedded systems requiring precise timing
• Portable electronic devices due to low voltage requirements

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD no-lead package footprint matches your PCB layout constraints. Check for any specific reflow soldering profile recommendations provided by the manufacturer to ensure reliable assembly.

Selection Notes

Select this component when a small form factor and low power consumption are critical. The 1.8V operation makes it suitable for modern low-voltage digital logic families. Consider the LVCMOS interface compatibility with your microcontroller or FPGA inputs. The integrated power-down feature offers an advantage in battery-operated applications where standby current reduction is necessary.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which focuses on miniature surface-mount oscillators. The series typically covers various frequencies within the standard range, offering consistent performance across different models. The 'PD' suffix indicates the inclusion of a power-down control pin, distinguishing it from continuous-operation variants.

Replacement Considerations

Direct substitutes must match the 10.024 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility if replacing with other manufacturers' parts. Ensure equivalent frequency stability and phase noise specifications are met for the application.
