25QHTF53-53.946-PD

Oscillators Overview

The 25QHTF53-53.946-PD is a quartz crystal oscillator manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a nominal frequency of 53.946 MHz and utilizes LVCMOS output logic. The device is designed for standard clock applications and supports a supply voltage of 2.5V. It features a power-down function via the standby pin, allowing for energy management in active systems. The component is housed in a compact 4-SMD, No Lead package, suitable for surface-mount assembly on printed circuit boards.

Oscillators Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes standby control for power-down functionality
• Designed for standard clock signal generation applications

Oscillators Applications

• General purpose clock signal generation
• Digital system timing references
• Embedded controller clock sources

Oscillators Procurement Notes

Verify the specific ordering suffix to ensure the correct output load and tolerance requirements are met. Confirm that the 2.5V supply voltage aligns with the target system design. Check RoHS compliance status if environmental regulations apply to the final assembly. Ensure the 4-SMD package dimensions fit within the available PCB real estate constraints.

Oscillators Selection Notes

Select this part when a 53.946 MHz clock source with LVCMOS outputs is required. Consider the 2.5V operating voltage range against other available supply options. Evaluate the 4-SMD footprint against board space limitations. Compare performance against alternative frequencies if the exact 53.946 MHz is not strictly necessary for the application timing.

Oscillators Part Context

This component belongs to the QHTF series of quartz crystal oscillators from Mercury Electronics. The series offers various frequencies and output types. The 25QHTF53 variant specifically denotes the 2.5V supply and LVCMOS output configuration. Mercury Electronics manufactures these devices as part of their broader portfolio of frequency control products including crystals and TCXOs.

Oscillators Replacement Considerations

Direct substitutes include other 25QHTF53 models with identical pinouts and electrical characteristics but different frequencies. Cross-reference with other manufacturers offering 53.946 MHz LVCMOS oscillators in 4-SMD packages. Verify that any replacement matches the 2.5V supply requirement and standby control functionality.
