Overview
The 18QHTF21-83.33333-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd, operating at a frequency of 83.33333 MHz. It utilizes LVCMOS output logic and functions with a supply voltage of 1.8V. The component features an Enable/Disable control function for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm. This surface-mount device is designed for integration into electronic circuits requiring precise clock signals.
Feature Summary
- Supports LVCMOS output logic for digital interface compatibility
- Includes enable/disable functionality for active power control
- Utilizes a small form factor 4-SMD no-lead package design
Applications
- General purpose clock signal generation in embedded systems
- Timing reference sources for digital communication interfaces
- Clock distribution in consumer electronics hardware
Procurement Notes
Verify the specific suffix 'OE' against official datasheets to confirm the enable/disable feature and voltage level. Ensure the 2.0x1.6mm footprint matches the PCB layout requirements. Confirm that the LVCMOS output voltage levels are compatible with the target system's input thresholds before finalizing procurement decisions.
Selection Notes
Select this component when a low-voltage 1.8V operation is required alongside a standard 83.33333 MHz frequency. The choice depends on the necessity for an enable pin to manage power states during idle periods. Consider the physical size constraints of the application, as the 2.0x1.6mm package is suitable for space-limited designs compared to larger oscillator packages.
Part Context
This part belongs to the Mercury Electronics XO series, which provides stable frequency references. The model number indicates the specific frequency, voltage, and package type within the manufacturer's lineup. Mercury Electronics has a history of manufacturing quartz crystals and oscillators, positioning this component as a standard timing solution for various electronic applications.
Replacement Considerations
Direct substitutes include other 83.33333 MHz LVCMOS oscillators in 2.0x1.6mm packages from different manufacturers, provided they support 1.8V operation and have compatible pinouts. Verify that any replacement also includes an enable/disable feature if power management is critical to the design.
