Overview
The 18QHTF21-49.000-OE is a standard frequency LVCMOS crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a nominal frequency of 49.000 MHz and utilizes a 4-SMD, No Lead package. The device functions with a supply voltage of 1.8V and includes an Enable/Disable control feature for power management. This component is designed for surface-mount applications requiring precise timing signals in electronic circuits.
Feature Summary
- Generates a stable 49.000 MHz clock signal using LVCMOS output levels
- Operates on a single 1.8V power supply rail
- Features integrated Enable/Disable functionality for power control
- Utilizes a compact 4-SMD, No Lead surface-mount package
Applications
- Digital logic circuit timing references
- Communication interface synchronization
- Microcontroller system clocks
- Embedded processor clock sources
Procurement Notes
Verify the specific operating temperature range and load capacitance requirements against the target application design before procurement. Confirm that the 1.8V supply voltage aligns with the system power architecture. Ensure the PCB footprint matches the 4-SMD, No Lead package dimensions to prevent assembly errors during manufacturing.
Selection Notes
Select this component when a low-voltage 1.8V operation is required alongside a standard LVCMOS output interface. The Enable/Disable pin allows for dynamic power management, making it suitable for battery-operated devices. Consider the 4-SMD form factor for space-constrained designs where through-hole mounting is not feasible.
