18QHTF21-85.600-OE

Overview

The 18QHTF21-85.600-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 85.6 MHz and utilizes LVCMOS output logic levels. The device is designed for low-voltage applications, functioning at 1.8V. It features an enable/disable control function to manage power consumption. The component is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm.

Feature Summary

• Supports LVCMOS output signal compatibility
• Includes enable and disable control functionality
• Operates on a 1.8V supply voltage

Applications

• General purpose timing circuits
• Digital communication systems
• Embedded system clock sources

Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply rail is stable and within the specified tolerance limits. Ensure the PCB footprint matches the 4-SMD, No Lead package dimensions precisely to avoid soldering issues during assembly.

Selection Notes

Select this component when a precise 85.6 MHz clock signal is required for LVCMOS-compatible digital logic. Consider the 1.8V operating voltage constraint and the need for active enable/disable control. The small 2.0x1.6 mm package makes it suitable for space-constrained designs requiring high-frequency stability.

Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series offers various frequencies and voltage options. The 'OE' suffix typically denotes a specific ordering or packaging variant, while the core specifications remain consistent with the standard XO family characteristics defined by the manufacturer.

Replacement Considerations

Direct substitutes include other 85.6 MHz LVCMOS oscillators in 4-SMD packages with 1.8V operation. Verify pinout compatibility and electrical parameters such as phase noise and jitter before substitution.
