18QHTF21-25.600-PD

Oscillators Overview

The 18QHTF21-25.600-PD is a standard crystal oscillator manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a fixed frequency of 25.6 MHz with an LVCMOS output logic level. The device requires a 1.8V supply voltage 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 timing applications requiring precise clock signals in space-constrained electronic systems.

Oscillators Feature Summary

• Supports low-voltage operation at 1.8V for efficient power consumption
• Includes a power-down standby mode to reduce current draw when inactive
• Provides stable LVCMOS output signals for digital circuit synchronization

Oscillators Applications

• Battery-powered portable devices requiring low current consumption
• Digital signal processing circuits needing precise clock references
• Communication modules utilizing standard LVCMOS interfaces

Oscillators Procurement Notes

Verify the specific ordering suffix and package type against the manufacturer's latest datasheet before procurement. Ensure compatibility with the target system's voltage requirements and physical footprint constraints. Confirm that the LVCMOS output levels align with the receiving logic inputs to prevent signal integrity issues during integration.

Oscillators Selection Notes

Select this component when a 25.6 MHz clock source is required with minimal power usage. The 1.8V supply specification makes it suitable for modern low-voltage digital designs. Consider the small 2.0x1.6mm package size for high-density PCB layouts where space is limited compared to larger oscillator packages.

Oscillators Part Context

This part belongs to the QHTF series of surface-mount oscillators from Mercury Electronics. The series typically offers various frequencies and voltage options within similar small form factors. The 'PD' suffix indicates the inclusion of a power-down control feature, distinguishing it from continuous-operation variants in the same product line.

Oscillators Replacement Considerations

Direct substitutes must match the 25.6 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package dimensions. Verify pinout compatibility and electrical characteristics with alternative manufacturers offering similar timing solutions.
