Overview
The 18QHTF21-13.5843-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a frequency of 13.5843 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features an enable/disable control function. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount applications requiring precise timing signals.
Feature Summary
- Supports LVCMOS output logic for digital interface compatibility
- Includes hardware enable/disable functionality for power management
- Utilizes a leadless SMD package for automated assembly
Applications
- General-purpose clock signal generation
- Embedded system timing references
- Consumer electronics circuit boards
Procurement Notes
Verify the specific frequency tolerance and load capacitance requirements against your design specifications before ordering. Confirm that the 1.8V supply voltage aligns with your target platform's power rails. Ensure the 4-SMD footprint matches your PCB layout constraints to guarantee proper soldering and mechanical stability during operation.
Selection Notes
Select this component when a low-voltage 1.8V supply is required alongside LVCMOS outputs. The enable/disable feature makes it suitable for battery-powered devices needing power optimization. Consider the small form factor if space constraints are critical within the electronic assembly.
Part Context
This part belongs to the 18QHTF21 series from Mercury Electronic Ind. Co., Ltd, a manufacturer specializing in quartz crystals and oscillators. The series typically offers various frequencies and voltage options. The 'OE' suffix likely denotes specific packaging or operational characteristics defined by the manufacturer.
Replacement Considerations
Direct substitutes may include other 1.8V LVCMOS oscillators in 4-SMD packages from manufacturers like Epson, NDK, or SiTime, provided the frequency and pinout compatibility are verified through official cross-reference tools.
