18QHTF21-48.750-PD

Oscillators Overview

The 18QHTF21-48.750-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 48.75 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes a standby (power down) control feature. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6mm.

Oscillators Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes standby power down functionality for energy management
• Compact surface-mount package design

Oscillators Applications

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

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the 4-SMD no-lead package footprint matches the PCB layout specifications to guarantee proper soldering and mechanical stability during assembly processes.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a precise 48.75 MHz clock signal. The LVCMOS output is suitable for direct interfacing with standard digital logic families. Consider the standby feature if power conservation during idle periods is a critical design constraint for the application environment.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series typically offers various frequencies and output types. The PD suffix indicates the inclusion of a power-down control pin, distinguishing it from continuously running variants within the same physical package family.

Oscillators Replacement Considerations

Direct substitutes include other 18QHTF21 series parts with identical 48.75 MHz frequency, 1.8V supply, and LVCMOS output logic. Verify pinout compatibility and thermal characteristics when cross-referencing with alternative manufacturers offering similar 2.0x1.6mm footprint oscillators.
