Overview
The 18QHTF21-48.896-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 48.896 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes an enable/disable control feature for power management. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications requiring precise timing signals.
Feature Summary
- Provides stable 48.896 MHz clock signal generation
- Integrates enable/disable functionality for power efficiency
- Supports low-voltage operation at 1.8V
- Utilizes LVCMOS output interface compatibility
Applications
- Telecommunications equipment timing
- Networking hardware synchronization
- Audio/video equipment clocking
Procurement Notes
Verify the specific ordering suffix against official Mercury Electronics documentation to ensure correct frequency and package configuration. Confirm that the OE suffix aligns with your required environmental or manufacturing specifications. Cross-reference the DigiKey part number 5672-18QHTF21-48.896-OE-ND for accurate sourcing details. Ensure compatibility with 1.8V logic levels in your target circuit design before procurement.
Selection Notes
Select this component when a precise 48.896 MHz reference is required for LVCMOS-compatible digital circuits. The 1.8V operating voltage makes it suitable for modern low-power systems. Consider the 4-SMD no-lead package for space-constrained PCB layouts. Verify that the enable/disable pin requirement fits your system's power management strategy.
Part Context
This oscillator belongs to Mercury Electronics' line of quartz-based frequency control products. The company has specialized in crystal and oscillator manufacturing since 1973. This specific model represents a standard XO variant within their portfolio, distinct from TCXOs or OCXOs due to its uncompensated temperature stability profile.
Replacement Considerations
Direct substitutes must match the 48.896 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify pinout compatibility and electrical characteristics with alternative manufacturers offering similar surface-mount oscillators.
