18QHTF21-24.577-PD

Oscillators Overview

The 18QHTF21-24.577-PD is a standard quartz crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 24.577 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes a standby (power down) feature for power management. It is housed in a compact 4-SMD, No Lead surface-mount package designed for high-density circuit board applications.

Oscillators Feature Summary

• Supports low-voltage operation at 1.8V
• Integrates standby mode for power reduction
• Provides LVCMOS compatible digital output signals

Oscillators Applications

• High-performance digital signal processing systems
• Communication equipment requiring precise clocking
• Embedded systems with strict power constraints

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your system design before ordering. Confirm that the 1.8V supply rail is stable within the operational limits defined in the official datasheet. Ensure the PCB footprint matches the 4-SMD No Lead package dimensions to guarantee proper solder joint integrity during assembly.

Oscillators Selection Notes

Select this component when a precise 24.577 MHz reference is required for LVCMOS interfaces. Consider the 1.8V operating voltage and standby capability if power efficiency is critical. Evaluate the small form factor against available board space constraints compared to larger through-hole or standard SMD oscillator packages.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series offers various frequencies tailored for digital circuits. The suffix PD indicates specific packaging or handling characteristics consistent with the manufacturer's standard product line definitions for this form factor.

Oscillators Replacement Considerations

Direct substitutes must match the 24.577 MHz frequency, LVCMOS output, and 1.8V supply voltage. Verify pin compatibility for the 4-SMD No Lead package. Cross-reference with other manufacturers offering similar low-profile oscillators ensuring identical electrical parameters.
