18QHTF21-24.256-PD

Oscillators Overview

The 18QHTF21-24.256-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a frequency of 24.256 MHz with an LVCMOS output logic level. The device requires a supply voltage of 1.8V and features a power-down (standby) function for energy management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm. This component is designed for applications requiring precise timing signals in low-voltage digital circuits.

Oscillators Feature Summary

• Supports Low Voltage CMOS (LVCMOS) output logic for direct interface with digital systems
• Includes standby mode capability to reduce power consumption during inactive periods
• Utilizes a surface-mount 4-SMD no-lead package for automated assembly compatibility

Oscillators Applications

• General purpose clock generation for embedded systems
• Timing reference for low-voltage microcontrollers
• Digital signal processing circuit synchronization

Oscillators Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against the target application design before procurement. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the PCB footprint matches the 2.0x1.6mm SMD package dimensions to prevent assembly errors. Cross-reference the manufacturer datasheet for any recent revisions or pinout changes.

Oscillators Selection Notes

Select this component when a fixed frequency of 24.256 MHz is required with minimal power usage. The LVCMOS output is suitable for standard logic families operating at 1.8V. Consider the small form factor if board space is limited. Verify that the ambient operating conditions fall within the specified industrial or commercial temperature limits defined in the official documentation.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which focuses on low-profile crystal oscillators. The series typically offers various frequencies and voltage options. The 'PD' suffix indicates the inclusion of a power-down control feature. Mercury Electronics specializes in quartz-based frequency control products, providing stable timing solutions for consumer and industrial electronics.

Oscillators Replacement Considerations

Direct substitutes must match the 24.256 MHz frequency, 1.8V supply, LVCMOS output, and 2.0x1.6mm package size. Check equivalent models from other manufacturers offering identical electrical characteristics and pin configurations. Ensure thermal and mechanical specifications are compatible with the existing design constraints.
