25QHTF22-74.1782-PD

Oscillators Overview

The 25QHTF22-74.1782-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 74.1782 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 2.5V and features a Standby (Power Down) function for power management. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications requiring precise timing signals.

Oscillators Feature Summary

• Supports standby mode for power reduction
• LVCMOS output interface compatibility
• Compact surface-mount package design

Oscillators Applications

• General clock signal generation
• Embedded system timing references
• Digital circuit synchronization

Oscillators Procurement Notes

Verify the specific ordering suffix 'PD' confirms the Standby (Power Down) functionality as distinct from other variants like 'OE'. Ensure the 2.5V supply requirement aligns with the target system's voltage rails. Confirm the 4-SMD, No Lead footprint matches the PCB layout specifications to ensure proper soldering and mechanical stability during assembly.

Oscillators Selection Notes

Select this component when a 74.1782 MHz reference is required with low-power standby capabilities. The LVCMOS output ensures compatibility with standard digital logic families. Consider the 2.5V operating voltage constraint against available power supplies. The SMD form factor suits automated assembly processes and space-constrained designs.

Oscillators Part Context

This model belongs to the 25QHTF22 series of standard crystal oscillators from Mercury Electronics. The series includes various frequencies and output logic types. The 'PD' suffix specifically denotes the inclusion of a power-down feature, differentiating it from enable/disable or always-on variants within the same physical package family.

Oscillators Replacement Considerations

Direct substitutes must match the 74.1782 MHz frequency, LVCMOS output, 2.5V supply, and 4-SMD No Lead package. Verify that any alternative part also supports the Standby (Power Down) function to maintain equivalent power management capabilities.
