18QHTF53-78.800-OE

Oscillators Overview

The 18QHTF53-78.800-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 78.8 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and includes an Enable/Disable control function for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 5.0mm x 3.2mm. The component is designed for operation within a specified temperature range typical for commercial applications.

Oscillators Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Features integrated Enable/Disable pin for active power management
• Utilizes a leadless SMD package for surface-mount assembly

Oscillators Applications

• General clock signal generation in electronic circuits
• Timing reference for digital systems requiring 78.8 MHz
• Embedded devices utilizing low-voltage logic interfaces

Oscillators Procurement Notes

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

Oscillators Selection Notes

Select this component when a fixed 78.8 MHz timing source is required with low power consumption capabilities. The LVCMOS output is suitable for direct interfacing with standard digital logic families. Consider the Enable/Disable feature if dynamic power saving is necessary for battery-operated or energy-efficient designs compared to continuously running oscillators.

Oscillators Part Context

This part belongs to the 18QHTF53 series from Mercury Electronics, which focuses on small-form-factor crystal oscillators. The series typically offers various frequencies and voltage options. Mercury Electronic Ind. Co., Ltd. is a established supplier of frequency control products, including quartz crystals and oscillators, with manufacturing history dating back several decades in Taiwan.

Oscillators Replacement Considerations

Direct substitutes must match the 78.8 MHz frequency, 1.8V supply, LVCMOS output, and 5.0x3.2mm package. Verify pinout compatibility for the OE pin. Cross-reference with other manufacturers offering similar SMD XO specifications if Mercury stock is unavailable.
