25QHTF21-22.7728-OE

Oscillators Overview

The 25QHTF21-22.7728-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 22.7728 MHz and utilizes LVCMOS output logic levels. The device supports voltage enable and disable functionality via a 2.5V control signal, allowing for power management in active circuits. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount assembly processes. This component provides stable clock signals for digital systems requiring precise timing synchronization.

Oscillators Feature Summary

• LVCMOS output interface for standard digital logic compatibility
• Voltage-controlled enable and disable capability
• Compact 4-SMD no-lead surface mount package design

Oscillators Applications

• Digital system clock generation
• Timing synchronization in embedded controllers
• Communication interface clock sources

Oscillators Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure correct frequency and package variant. Confirm that the 2.5V enable logic level matches the system control voltage. Request the official specification document from Mercury Electronics for final electrical parameter validation before integration.

Oscillators Selection Notes

Select this oscillator when a 22.7728 MHz clock source with LVCMOS outputs is required. Ensure the application circuit supports the 2.5V enable/disable control signal. Verify that the 4-SMD footprint aligns with the PCB layout constraints. Consider thermal and environmental specifications if operating outside standard conditions.

Oscillators Part Context

This part belongs to the 25QHTF21 series of standard oscillators from Mercury Electronics. The series offers various frequencies with consistent LVCMOS output characteristics. The -OE suffix typically denotes a specific packaging or tape-and-reel configuration within the product line, distinct from other suffixes like -PD.

Oscillators Replacement Considerations

Direct substitutes must match the 22.7728 MHz frequency, LVCMOS output type, 2.5V enable logic, and 4-SMD package. Verify pinout compatibility and electrical parameters with alternative manufacturers' components offering similar timing stability.
