18QHTF21-15.375-OE

Oscillators Overview

The 18QHTF21-15.375-OE is a 15.375 MHz crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a supply voltage of 1.8V and utilizes an LVCMOS output signal format. The device features an Enable/Disable control function for power management. It is housed in a compact 4-SMD surface-mount package with dimensions of 2.0mm x 1.6mm. This component is designed as a standard XO (Crystal Oscillator) suitable for applications requiring precise frequency generation within low-voltage digital circuits.

Oscillators Feature Summary

• Supports LVCMOS output logic levels for direct interface with digital components
• Includes an active-low or high enable/disable pin for dynamic power control
• Utilizes a miniature 4-SMD footprint to optimize board space

Oscillators Applications

• Clock generation for low-voltage microprocessors
• Timing reference for communication interfaces
• Synchronization sources in portable electronic devices

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD package dimensions fit within your PCB layout constraints. Request the official datasheet from Mercury Electronic Ind. Co. Ltd to validate electrical characteristics and operating temperature ranges for your specific application environment.

Oscillators Selection Notes

Select this model when a 15.375 MHz clock source is required in a 1.8V system. Consider the LVCMOS output compatibility with your downstream logic family. Evaluate the need for an enable pin to manage power consumption during idle states. Compare the 2.0x1.6mm package size against available board real estate. Ensure the standard XO performance meets your jitter and stability specifications without requiring additional filtering.

Oscillators Part Context

Mercury Electronic Ind. Co. Ltd has been manufacturing frequency control products since 1973, establishing itself as a pioneer in quartz crystal production in Taiwan. The company expanded its capabilities from lead-type crystals to surface-mount technologies, covering a wide frequency range from several KHz to hundreds of MHz. The 18QHTF21 series represents their surface-mount oscillator offerings, designed for modern compact electronics.

Oscillators Replacement Considerations

Direct substitutes must match the 15.375 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify equivalent electrical parameters such as phase noise and stability. Check if alternative manufacturers offer compatible pinouts and enable functions. Cross-reference part numbers from other suppliers ensuring identical form factor and voltage levels to maintain circuit integrity.
