Oscillators Procurement Notes
Verify the specific frequency tolerance and load capacitance requirements against your design specifications before ordering. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the PCB footprint matches the 2.0x1.6mm SMD package dimensions to guarantee proper soldering and mechanical stability during assembly processes.
Oscillators Selection Notes
Select this component when a low-voltage 1.8V operation is required alongside a standard LVCMOS interface. The small 2.0x1.6mm form factor makes it suitable for space-constrained designs. Consider the standby feature if power efficiency during idle states is a priority for the application environment.
Oscillators Part Context
This part belongs to the 18QHTF series of crystal oscillators from Mercury Electronic Ind. Co., Ltd. The series offers various frequencies within the same physical package, allowing for design flexibility. Mercury Electronics specializes in quartz crystals and timing devices, providing standardized solutions for frequency control applications across multiple industries.
Oscillators Replacement Considerations
Direct substitutes include other 21.4 MHz LVCMOS oscillators in 4-SMD packages with 1.8V operation. Verify pin compatibility and electrical parameters such as phase noise and jitter before swapping components.
