18QHTF21-84.6963-OE

Overview

The 18QHTF21-84.6963-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a frequency of 84.6963 MHz and utilizes LVCMOS output logic. The device requires 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 2.0mm x 1.6mm. This component is designed for applications requiring precise timing signals within low-voltage digital systems.

Feature Summary

• Provides stable clock signals at 84.6963 MHz using LVCMOS output
• Operates on a single 1.8V power supply
• Includes hardware enable and disable functionality for power management
• Utilizes a small surface-mount package suitable for space-constrained designs

Applications

• Digital signal processing circuits
• Communication equipment clocking
• Embedded system timing references
• Consumer electronics mainboards

Procurement Notes

Verify the specific suffix OE against the manufacturer's datasheet to confirm pinout and electrical characteristics match your design requirements. Ensure the 1.8V supply rail is stable and within tolerance before integration. Confirm that the 4-SMD no-lead package footprint aligns with your PCB layout guidelines to prevent soldering defects during assembly.

Selection Notes

Select this oscillator when a fixed 84.6963 MHz frequency is required for synchronous data transmission or processing. The LVCMOS interface ensures compatibility with standard logic families operating at 1.8V. Consider the enable pin if dynamic power saving is necessary. Verify temperature range specifications against your operational environment constraints prior to final selection.

Part Context

This part belongs to the QHTF series of surface-mount oscillators from Mercury Electronics. The series typically offers various frequencies and voltage options within a standardized small form factor. The 18QHTF21 designation indicates specific mechanical and electrical parameters consistent with the family's general specifications for low-power timing applications.

Replacement Considerations

Direct substitutes must match the 84.6963 MHz frequency, 1.8V supply, LVCMOS output, and 2.0x1.6mm package size. Check Mercury Electronics documentation for alternative part numbers within the same series that share identical pinouts and electrical profiles to ensure drop-in compatibility without circuit redesign.
