18QHTF21-100.080-PD

Overview

The 18QHTF21-100.080-PD is a standard crystal oscillator manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a frequency of 100.08 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes a power-down feature for standby control. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm.

Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Integrates a power-down pin for standby mode management
• Designed for surface mount assembly in small form factors

Applications

• High-speed data communication systems
• Digital signal processing circuits
• Network infrastructure equipment

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 specifications to guarantee proper soldering and mechanical stability during operation.

Selection Notes

Select this component when a precise 100.08 MHz clock source is required for LVCMOS-compatible digital logic. Consider the low profile and small footprint suitable for space-constrained designs. Evaluate the power consumption benefits provided by the standby capability if energy efficiency is a priority in the application environment.

Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series typically offers various frequencies and voltages within a standardized 2.0x1.6mm package. The 'PD' suffix indicates the inclusion of a power-down control function, distinguishing it from non-controllable variants in the same physical package family.

Replacement Considerations

Direct replacements must match the 100.08 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility and electrical characteristics such as jitter and phase noise to ensure seamless integration without circuit modification.
