18QHTF21-80.160-PD

Overview

The 18QHTF21-80.160-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 80.16 MHz and utilizes LVCMOS output logic. The device requires a supply voltage of 1.8V and features a standby or 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. This component is designed for surface mount applications requiring precise timing signals.

Feature Summary

• Supports standby mode for power reduction
• Utilizes LVCMOS output logic levels
• Compact surface-mount package design

Applications

• Battery-powered portable devices
• General electronic timing circuits

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the PCB footprint matches the 4-SMD, No Lead package dimensions to prevent assembly errors during manufacturing.

Selection Notes

Select this model when a low-voltage 1.8V operation is required alongside a specific 80.16 MHz frequency. Consider the small form factor for space-constrained designs. Evaluate the need for a power-down feature if battery life optimization is a priority for the target application.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies within a standardized 1.8V LVCMOS package. The series provides consistent electrical characteristics across different frequency options, allowing for easier supply chain management when designing multi-frequency systems.

Replacement Considerations

Check datasheets for compatible oscillators offering identical 80.16 MHz frequency, 1.8V supply, and LVCMOS output. Verify pin compatibility and package dimensions to ensure direct replacement without PCB redesign.
