18QHTF21-9.509-OE

Overview

The 18QHTF21-9.509-OE is a quartz crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 9.509 MHz with an LVCMOS output signal type. The device functions at a supply voltage of 1.8V and includes enable/disable control capabilities. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm.

Feature Summary

• Supports standard enable and disable functionality for power management
• Provides LVCMOS output signals compatible with digital logic interfaces
• Utilizes a small surface-mount package design for space-constrained applications

Applications

• Clock generation for embedded systems
• Timing reference for low-power digital circuits
• Signal synchronization in portable electronic devices

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 no-lead package footprint matches your PCB layout constraints. Check for RoHS compliance status if required by your manufacturing standards. Request official datasheets to validate operational temperature ranges and stability specifications.

Selection Notes

Select this component when a precise 9.509 MHz timing source is required for LVCMOS-compatible logic. Consider the 1.8V operating voltage for compatibility with modern low-voltage microcontrollers. Evaluate the small 2.0x1.6mm package size against available board space. Verify that the enable/disable feature meets your power consumption goals. Compare performance metrics such as jitter and stability against alternative oscillators in the QuikXO series.

Part Context

This part belongs to Mercury Electronics' QuikXO series, which focuses on fast-delivery CMOS output clock oscillators. The series offers various frequencies within a defined range, typically starting from 1.0 MHz. These components are designed for applications requiring reliable timing signals in a compact form factor, supporting both standard and custom frequency options.

Replacement Considerations

Direct substitutes may include other models from the 18QHTF21 series with different frequencies but identical pinouts and electrical characteristics. Verify compatibility with any Mercury Electronics oscillator offering the same 4-SMD package and 1.8V LVCMOS output. Cross-reference with generic 9.509 MHz XO components only if pin compatibility and voltage levels match exactly.
