18QHTF21-65.010-OE

Overview

The 18QHTF21-65.010-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 65.010 MHz and utilizes LVCMOS output logic. The device is designed for low-voltage applications, requiring a supply voltage of 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 2.0mm x 1.6mm. This surface-mount configuration facilitates automated assembly and integration into space-constrained electronic circuits.

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 4-SMD no-lead package dimensions provided in the official datasheet. Check for any specific handling instructions regarding electrostatic discharge sensitivity during storage and installation.

Selection Notes

Select this component when a precise 65.010 MHz clock source is required in a low-power environment. The LVCMOS output is suitable for direct interfacing with standard digital logic families. Consider the enable/disable feature if power management is critical. The small form factor makes it ideal for dense PCB layouts where space is limited compared to larger through-hole or standard SMD packages.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which focuses on low-voltage, high-frequency oscillators. The series typically offers various frequencies within the same physical footprint, allowing for design flexibility. Mercury Electronics is a established manufacturer of frequency control products, providing quartz crystals and oscillators for industrial and consumer electronics markets globally.

Replacement Considerations

Direct replacements must match the 65.010 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 if specified in the original design. Consult the manufacturer's cross-reference list for approved substitutes.
