18QHTF21-80.100-PD

Overview

The 18QHTF21-80.100-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 80.1 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes a standby or power-down feature for energy management. It is housed in a compact 4-SMD, No Lead surface-mount package with dimensions of 2.00mm x 1.60mm. This component is designed for applications requiring precise timing signals within low-voltage digital systems.

Feature Summary

• Integrates LVCMOS output logic for direct interfacing with digital circuits
• Supports standby mode to reduce power consumption during idle periods
• Utilizes a leadless surface-mount package for automated assembly compatibility

Applications

• Digital signal processing equipment requiring stable clock sources
• Communication modules utilizing LVCMOS interfaces
• Embedded systems operating at 1.8V supply levels

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to ensure correct configuration. Confirm that the PD suffix aligns with the required power-down functionality. Cross-reference the frequency specification of 80.1 MHz with system requirements. Ensure the 1.8V supply voltage matches the target circuit design before procurement.

Selection Notes

Select this component when a precise 80.1 MHz clock signal is required for LVCMOS-compatible devices. Consider the 1.8V operating voltage constraint for power budgeting. Evaluate the need for a power-down feature if energy efficiency is critical. The small 4-SMD footprint suits space-constrained PCB layouts compared to larger packages.

Part Context

This part belongs to the Mercury Electronics XO series, which provides standard frequency control solutions. The manufacturer specializes in quartz crystal products with decades of industry experience. The 18QHTF21 series typically offers various frequencies and voltage options within a consistent form factor for flexible design integration.

Replacement Considerations

Direct substitutes may include other 80.1 MHz LVCMOS oscillators in 2.0x1.6mm packages from compatible manufacturers. Verify pinout compatibility and electrical specifications such as load capacitance and drive strength. Alternative parts must support the 1.8V supply and standby functionality if required by the design.
