18QHTF21-6.000-OE

Overview

The 18QHTF21-6.000-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 6.000 MHz and utilizes LVCMOS output logic. The device is designed for low-voltage applications, requiring a 1.8V supply voltage. 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 2.0 x 1.6 mm. This surface-mount oscillator is suitable for timing applications requiring precise clock signals in space-constrained electronic designs.

Feature Summary

• LVCMOS output logic for digital interface compatibility
• Integrated enable/disable control functionality
• Compact 4-SMD no-lead surface mount package

Applications

• General-purpose clock signal generation
• Digital circuit timing references
• Embedded system clock sources

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your design specifications before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the PCB footprint matches the 2.0x1.6mm 4-SMD no-lead package dimensions to guarantee proper soldering and mechanical stability during assembly processes.

Selection Notes

Select this component when a low-profile, low-voltage oscillator is required for 6 MHz timing applications. Consider the LVCMOS output compatibility with downstream digital logic families. Evaluate the enable/disable feature if power management is critical. Compare physical size constraints against alternative packages to ensure the 2.0x1.6mm form factor fits within the designated board area without interfering with surrounding components.

Part Context

This part belongs to the Mercury Electronics 18QHTF series of surface-mount crystal oscillators. The series typically offers various frequencies and voltage options. Mercury Electronics is a specialized manufacturer of frequency control products, including quartz crystals and oscillators, with a focus on providing reliable timing solutions for industrial and consumer electronics markets.

Replacement Considerations

Direct substitutes must match the 6.000 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Verify pinout compatibility and electrical characteristics such as phase noise and jitter. Consult manufacturer cross-reference lists for equivalent parts from other suppliers offering identical specifications.
