18QHTF21-100.060-PD

Overview

The 18QHTF21-100.060-PD is a 100.06 MHz crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It utilizes LVCMOS output logic and operates on a 1.8V supply voltage. The device features a Standby (Power Down) function for energy management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.00mm x 1.60mm.

Feature Summary

• Supports LVCMOS output logic for standard digital interfacing
• Integrates a Standby (Power Down) mode to reduce power consumption
• Designed for surface mount assembly in space-constrained applications

Applications

• Battery-powered portable devices
• General purpose clock signal generation
• Standard digital system timing references

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's power rails. Ensure the 4-SMD no-lead package footprint matches the PCB layout constraints. Cross-reference the manufacturer datasheet for precise electrical characteristics and thermal handling specifications.

Selection Notes

Select this component when a 100.06 MHz clock source is required with low voltage operation. The LVCMOS interface ensures compatibility with standard logic families. The integrated power-down feature makes it suitable for applications requiring active power management. Consider the small form factor for dense board layouts.

Part Context

This part belongs to the 18QHTF21 series of oscillators from Mercury Electronics. The series offers various frequencies with consistent 1.8V operation and LVCMOS outputs. The 'PD' suffix indicates the inclusion of a power-down control pin or function, distinguishing it from standard continuous-operation variants within the same package family.

Replacement Considerations

Direct substitutes include other 18QHTF21 series parts with identical package and voltage but different frequencies, such as 18QHTF21-51.200-PD or 18QHTF21-68.080-PD. Verify frequency accuracy and phase noise specifications when cross-referencing with alternative manufacturers.
