18QHTF21-80.084-PD

Overview

The 18QHTF21-80.084-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 80.084 MHz with an LVCMOS output logic level. The device supports a supply voltage of 1.8V and includes a standby or power-down function for energy management. It is housed in a compact 4-SMD, no-lead package with dimensions of 2.0 x 1.6 mm. This component is designed for applications requiring precise timing signals within low-voltage digital systems.

Feature Summary

• Supports LVCMOS output logic for direct interface with digital circuits
• Includes standby mode functionality to reduce power consumption during idle periods
• Utilizes a small form factor SMD package suitable for space-constrained designs

Applications

• Digital signal processing systems requiring clock synchronization
• Communication equipment utilizing standard frequency references
• Embedded control systems operating on low voltage supplies

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the system design specifications before procurement. Ensure that the 1.8V supply voltage aligns with the target circuit's power rails. Confirm that the 4-SMD no-lead package footprint matches the PCB layout constraints. Check for any specific handling instructions related to the surface mount technology used in this component.

Selection Notes

Select this oscillator when a precise 80.084 MHz reference is needed in a low-profile package. Consider the LVCMOS output compatibility with the downstream logic family. Evaluate the power-down feature if battery life or thermal management is a critical design constraint. Compare the physical dimensions against available board space to ensure proper fitment within the assembly.

Part Context

This component belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronics Ind. Co. Ltd. The series offers various frequencies and voltage options within a standardized 2.0x1.6 mm footprint.
