18QHTF21-100.197-OE

Overview

The 18QHTF21-100.197-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 100.197 MHz and utilizes LVCMOS output logic. The component supports a supply voltage of 1.8V and includes an enable/disable control function for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm. The device is designed for applications requiring precise timing signals within a specified operating temperature range.

Feature Summary

• Provides stable clock signals using LVCMOS output logic
• Features integrated enable/disable control functionality
• Utilizes a compact surface-mount package design

Applications

• General purpose digital circuit timing
• Embedded system clock generation
• Communication interface synchronization

Procurement Notes

Verify the specific suffix (OE) against official Mercury Electronics documentation to confirm the exact electrical characteristics and pinout configuration. Ensure that the required operating temperature range and load conditions match the application specifications before procurement. Cross-reference the part number with authorized distributors to validate authenticity and availability status.

Selection Notes

Select this component when a 100.197 MHz clock source with LVCMOS compatibility is required. Consider the 1.8V supply constraint and the need for an enable pin during system design. Evaluate the 2.0x1.6mm footprint against available PCB space. Compare performance requirements such as phase noise and stability against alternative oscillators if stricter timing constraints exist.

Part Context

This model belongs to the Mercury Electronics XO series, which focuses on standard frequency control solutions. The brand has specialized in quartz crystals and oscillators since 1973. This specific part represents a low-profile surface-mount option suitable for modern electronic devices requiring reliable timing references in small form factors.

Replacement Considerations

Direct substitutes must match the 100.197 MHz frequency, LVCMOS output, 1.8V supply, and 4-SMD no-lead package. Verify pin compatibility and thermal characteristics. Consult manufacturer cross-reference lists for approved equivalents.
