Overview
The 18QHTF21-13.224-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 13.224 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and includes a standby or power-down function for energy management. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount assembly.
Feature Summary
- Supports LVCMOS output logic for digital interface compatibility
- Includes standby mode capability for power reduction
- Utilizes a leadless SMD package for space-efficient mounting
Applications
- General clock signal generation in electronic circuits
- Timing reference for low-voltage digital systems
- Embedded devices requiring precise frequency control
Procurement Notes
Verify the specific ordering suffix to ensure the correct package variant and tape-and-reel configuration if applicable. Confirm that the 1.8V supply requirement aligns with the target system design. Check for any specific handling instructions related to the leadless SMD form factor during assembly.
Selection Notes
Select this component when a 13.224 MHz clock source is required with LVCMOS outputs. Ensure the application supports the 1.8V operating voltage. Consider the physical dimensions of the 4-SMD No Lead package against available PCB real estate. Verify thermal requirements for the intended operating temperature range.
Part Context
This part belongs to the Mercury Electronics XO series, which provides standard frequency control solutions. The model number indicates a 13.224 MHz frequency variant within the 18QHTF21 family. These oscillators are designed for reliability in consumer and industrial electronics applications requiring stable timing signals.
Replacement Considerations
Direct substitutes include other 13.224 MHz LVCMOS oscillators in compatible packages from the same manufacturer, such as the 18QHTF21-18.1059-PD or 18QHTF21-51.200-PD, provided the frequency difference is acceptable for the circuit design.
