18QHTF21-25.0025-PD

Oscillators Overview

The 18QHTF21-25.0025-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a frequency of 25.0025 MHz with an LVCMOS output logic level. The device requires a supply voltage of 1.8V and features a Standby (Power Down) control function. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm.

Oscillators Feature Summary

• Supports Low Voltage CMOS (LVCMOS) output interface for digital circuit compatibility
• Includes Standby (Power Down) functionality to reduce power consumption when inactive
• Utilizes a surface-mount 4-SMD No Lead package for automated assembly integration

Oscillators Applications

• General-purpose timing clock generation in embedded systems
• Synchronization sources for microcontrollers and processors
• Data communication interfaces requiring precise frequency references

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's power rails. Ensure the 2.0x1.6mm footprint matches the PCB layout constraints. Cross-reference the datasheet for any specific handling or reflow soldering profile recommendations provided by the manufacturer.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a standard LVCMOS output. The small 2.0x1.6mm form factor makes it suitable for space-constrained designs. Consider the standby feature if power management during idle states is a priority. Compare against other frequencies in the 18QHTF21 series if different timing speeds are needed while maintaining the same package and electrical characteristics.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronic Ind. Co., Ltd. The series typically offers various standard frequencies with consistent electrical specifications and packaging. The 'PD' suffix indicates the inclusion of a power-down pin or function. Mercury Electronics specializes in quartz-based frequency control products, including crystals, filters, and oscillators, serving global electronics manufacturing needs.

Oscillators Replacement Considerations

Direct substitutes within the same series include 18QHTF21-25.0000-PD and 18QHTF21-25.0000-PD variants with identical packages and voltages but different frequencies. Other Mercury models sharing the 18QHTF21 footprint and 1.8V LVCMOS specification may be compatible if frequency adjustments are acceptable.
