Overview
The 18QHTF21-13.3632-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 13.3632 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and includes an enable/disable control function. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm.
Feature Summary
- Integrates LVCMOS output logic for standard digital interface compatibility
- Features active enable and disable control functionality via the OE pin
- Utilizes a leadless surface-mount package design for automated assembly
Applications
- General clock signal generation in electronic circuits
- Timing reference sources for low-voltage digital systems
- Embedded applications requiring precise frequency stability
Procurement Notes
Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the PCB footprint matches the 4-SMD no-lead package dimensions to prevent soldering defects during assembly.
Selection Notes
Select this component when a fixed frequency of 13.3632 MHz is required with LVCMOS outputs. Consider the 1.8V operating voltage and the need for an enable/disable feature. Evaluate the physical size constraints of the 2.0x1.6mm package against available board space.
Part Context
This model belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies within the same form factor. The series provides standardized timing solutions with consistent electrical characteristics across different frequency options, facilitating inventory management for multi-frequency designs.
Replacement Considerations
Direct substitutes include other 18QHTF21 variants with identical package and voltage specifications but different frequencies, such as 18QHTF21-13.768-OE or 18QHTF21-21.200-OE, provided the frequency difference is acceptable for the application.
