25QHTF21-1.500-PD

Oscillators Overview

The 25QHTF21-1.500-PD is a 1.5 MHz crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates with LVCMOS output levels and requires a 2.5V power supply. The device features a standby or power-down function to reduce consumption. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm.

Oscillators Feature Summary

• LVCMOS output interface for standard logic compatibility
• Integrated standby mode for power management
• Compact surface-mount footprint

Oscillators Applications

• General purpose clock generation
• Embedded system timing references
• Consumer electronics control circuits

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your design specifications before ordering. Confirm that the 2.5V supply voltage aligns with your system's power rails. Ensure the 4-SMD no-lead package size fits within your PCB layout constraints. Check for any RoHS compliance documentation if required for your manufacturing process.

Oscillators Selection Notes

Select this component when a low-frequency 1.5 MHz reference is needed with minimal power usage. The LVCMOS output simplifies interfacing with digital logic without additional level shifting. The small form factor is suitable for space-constrained designs. Consider the standby feature if power efficiency is a critical design parameter.

Oscillators Part Context

This part belongs to the 25QHTF21 series of surface-mount oscillators from Mercury Electronics. The series typically offers various frequencies with consistent 2.5V operation and LVCMOS outputs. The 'PD' suffix indicates the inclusion of a power-down capability, distinguishing it from standard continuous-operation variants within the same package family.

Oscillators Replacement Considerations

Direct substitutes include other 1.5 MHz XO devices in 2.0x1.6mm packages with LVCMOS outputs and 2.5V operation. Verify pinout compatibility and electrical characteristics such as jitter and stability before swapping manufacturers.
