25QHTF57-78.1758-OE

Oscillators Overview

The 25QHTF57-78.1758-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 78.1758 MHz and requires a 2.5V supply voltage. The device features an LVCMOS output signal type, ensuring compatibility with standard logic interfaces. A key functional attribute is the integrated Enable/Disable control pin, allowing for power management in active circuits. The component is housed in a compact 4-SMD, No Lead package, designed for surface-mount assembly on printed circuit boards.

Oscillators Feature Summary

• LVCMOS output interface for standard logic compatibility
• Integrated enable/disable functionality for power control
• Compact 4-SMD no-lead surface mount package

Oscillators Applications

• General clock generation for digital systems
• Timing reference for communication modules
• Embedded system clock sources

Oscillators Procurement Notes

Verify the specific suffix 'OE' against manufacturer documentation to confirm the enable/disable feature and voltage level. Ensure the 4-SMD footprint matches the target PCB layout. Cross-reference the 78.1758 MHz frequency requirement with system specifications to avoid timing mismatches. Confirm supply voltage tolerance aligns with the 2.5V nominal rating.

Oscillators Selection Notes

Select this model when a precise 78.1758 MHz clock source is needed with low-power standby capabilities. The LVCMOS output suits standard CMOS logic families. The small 4-SMD form factor is ideal for space-constrained designs. Consider the 2.5V operating voltage to ensure compatibility with existing power rails without additional regulation.

Oscillators Part Context

This part belongs to the 25QHTF57 series of standard oscillators from Mercury Electronics. The series typically offers various frequencies within a consistent 4-SMD package. The 'OE' suffix denotes specific operational characteristics, likely related to the enable function or packaging variant, distinguishing it from other series members like the '-PD' variant.

Oscillators Replacement Considerations

Direct substitutes must match the 78.1758 MHz frequency, 2.5V supply, LVCMOS output, and 4-SMD package. Verify that any replacement also includes the enable/disable control feature. Check pinout compatibility to ensure seamless integration without PCB redesign.
