18QHTF21-84.7063-OE

Overview

The 18QHTF21-84.7063-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 84.7063 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features an enable/disable control function. It is housed in a compact 4-SMD, no lead package with dimensions of 2.00mm x 1.60mm.

Feature Summary

• Integrates LVCMOS output logic for digital interface compatibility
• Supports active enable and disable control states
• Operates on a single 1.8V power supply rail

Applications

• High-speed data communication interfaces
• Clock generation for embedded processors
• Network synchronization 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 architecture. Ensure the 4-SMD footprint matches the PCB layout specifications to guarantee proper soldering and mechanical stability during assembly.

Selection Notes

Select this component when a precise 84.7063 MHz clock signal is required for low-voltage digital systems. The choice depends on the necessity for LVCMOS outputs and the availability of a 1.8V power source. Consider the physical size constraints of the application, as the 2.0x1.6mm package is suitable for space-sensitive designs requiring integrated enable functionality.

Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series typically offers various frequency options within a standardized small outline package. These components are engineered for applications demanding stable clock signals in portable and industrial electronics where power efficiency and board space are critical factors.

Replacement Considerations

Direct substitutes must match the 84.7063 MHz frequency, 1.8V operating voltage, LVCMOS output type, and 4-SMD 2.0x1.6mm package dimensions. Verify that any alternative component supports the same enable/disable control mechanism to maintain functional equivalence in the existing circuit design.
