Overview
The 18QHTF21-93.200-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 93.2 MHz and utilizes LVCMOS output logic levels. The device is designed for low-voltage applications, functioning at a supply voltage of 1.8V. A key functional characteristic is the inclusion of an enable/disable control pin, allowing for power management during inactive periods. The component is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm, suitable for space-constrained surface-mount designs.
Feature Summary
- Supports enable/disable functionality via dedicated control pin
- Utilizes LVCMOS output interface for digital compatibility
- Operates at 1.8V supply voltage for low-power efficiency
Applications
- Embedded systems requiring precise clock timing
- Consumer electronics with limited power budgets
- Industrial control modules needing stable frequency sources
Procurement Notes
Verify that the specific part number matches the required 93.2 MHz frequency and 1.8V operating voltage. Confirm the package type is 4-SMD, No Lead with 2.0x1.6 mm dimensions. Ensure the enable/disable feature is necessary for the design. Check for RoHS compliance status if environmental regulations apply to the final product assembly.
Selection Notes
Select this component when a low-profile, low-voltage oscillator with power control is required. The 1.8V specification limits suitability for higher voltage domains. The small 2.0x1.6 mm footprint aids in dense PCB layouts. Consider the LVCMOS output swing against the input requirements of the connected load circuitry to ensure signal integrity.
Part Context
This model belongs to the Mercury Electronics 18QHTF21 series of surface-mount crystal oscillators. The series typically offers various frequencies and voltage options within a standardized small outline package. The suffix indicates specific electrical characteristics and packaging details consistent with the manufacturer's standard product line for general-purpose clock generation.
Replacement Considerations
Direct substitutes include other 93.2 MHz LVCMOS oscillators in 4-SMD packages from different manufacturers, provided they support 1.8V operation and have compatible pinouts. Verify that any replacement also includes an enable/disable function if power management is critical to the application.
