18QHTF21-102.000-OE

Overview

The 18QHTF21-102.000-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a frequency of 102.000 MHz and utilizes LVCMOS output logic. The device is designed for low-voltage applications, supporting 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 2.0x1.6 mm. This series is part of the QuikXO line, emphasizing fast delivery and surface-mount compatibility for modern electronic designs.

Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes Enable/Disable pin for active power management
• Utilizes a compact 4-SMD No Lead surface-mount package

Applications

• General-purpose clock signal generation in embedded systems
• Timing reference for microcontrollers and processors
• Data communication interfaces requiring precise frequency stability

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure the correct voltage and package variant. Confirm that the 1.8V supply requirement aligns with your system design. Check for availability through authorized distributors as lead times may vary. Ensure proper handling procedures are followed due to the small form factor.

Selection Notes

Select this component when a 102.000 MHz clock source is required in a space-constrained environment. The 1.8V operating voltage makes it suitable for low-power portable devices. Consider the Enable/Disable feature if power efficiency during idle states is a priority. Compare against other QuikXO variants if different frequencies or voltages are needed.

Part Context

This oscillator belongs to Mercury's QuikXO series, which focuses on rapid delivery of standard CMOS output clocks. The 18QHTF21 series typically offers various frequencies and voltage options within a standardized footprint. It serves as a timing solution for applications requiring reliable quartz-based frequency generation without the complexity of programmable oscillators.

Replacement Considerations

Direct substitutes must match the 102.000 MHz frequency, 1.8V supply, LVCMOS output, and 2.0x1.6mm package. Verify pinout compatibility and electrical characteristics before substitution. Other Mercury part numbers in the same series may offer alternative frequencies but require validation of functional equivalence.
