18QHTF21-100.00075-PD

Overview

The 18QHTF21-100.00075-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 100.00075 MHz and utilizes LVCMOS output logic levels. The device is designed for a supply voltage of 1.8V and includes a standby or power-down function to manage energy consumption. It is housed in a compact 4-SMD, no lead package with dimensions of 2.0x1.6 mm, suitable for surface-mount applications requiring precise timing signals.

Feature Summary

• Supports LVCMOS output interface for digital compatibility
• Includes standby mode for power management
• Compact 4-SMD no lead package design

Applications

• Digital signal processing systems
• Communication equipment timing
• Embedded control circuits

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the official datasheet before procurement. Ensure the 1.8V supply voltage aligns with the target system design. Confirm that the 4-SMD no lead package footprint matches the PCB layout constraints. Cross-reference the suffix PD with manufacturer documentation to confirm availability and exact electrical specifications.

Selection Notes

Select this component when a 100.00075 MHz clock source is required with low voltage operation. The LVCMOS output ensures direct interfacing with standard digital logic without additional level shifting. The integrated standby feature aids in power-sensitive designs. Verify thermal performance and stability requirements against the official specifications for the intended operating environment.

Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series offers various frequencies within a standardized 2.0x1.6 mm footprint. The 100.00075 MHz variant provides a specific high-frequency clock solution. It shares common packaging and electrical characteristics with other models in the family, differing primarily in output frequency.

Replacement Considerations

Direct substitutes include other 18QHTF21 series parts with identical pinouts and voltage ratings but different frequencies, such as 18QHTF21-100.0025-PD. Ensure any replacement maintains the LVCMOS output type and 1.8V supply requirement. Verify mechanical compatibility of the 4-SMD no lead package.
