18QHTF21-23.600-PD

Oscillators Overview

The 18QHTF21-23.600-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a fixed frequency of 23.6 MHz and utilizes LVCMOS output logic levels. The device is designed for low-power applications, featuring a supply voltage of 1.8V and an integrated standby or power-down mode to minimize energy consumption when not in active use. The component is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm, suitable for space-constrained surface-mount designs.

Oscillators Feature Summary

• Supports low-voltage operation at 1.8V with integrated power-down functionality
• Delivers standard LVCMOS output signals for digital interface compatibility
• Utilizes a compact 4-SMD no-lead package for efficient board space utilization

Oscillators Applications

• Portable electronic devices requiring low power consumption
• Digital communication systems utilizing LVCMOS interfaces
• Embedded control circuits needing precise timing references

Oscillators Procurement Notes

Verify the specific ordering suffix and frequency tolerance against project requirements before procurement. Ensure that the 1.8V supply voltage aligns with the target system's power rails. Confirm the availability of the power-down pin configuration if standby functionality is critical for the design. Cross-reference the package dimensions with the PCB footprint library to ensure mechanical compatibility during assembly.

Oscillators Selection Notes

Select this component when a small form factor and low voltage operation are primary constraints. The LVCMOS output is suitable for direct interfacing with standard digital logic families without additional level shifting. Consider the power-down feature for battery-operated applications where standby current reduction is essential. Evaluate the thermal performance and operating temperature range relative to the intended environment.
