Procurement Notes
Verify the specific frequency tolerance and load capacitance requirements against your design specifications before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD no lead package footprint matches your PCB layout to guarantee proper soldering and mechanical stability during operation.
Selection Notes
Select this component when a precise 105.63 MHz clock source is required with low voltage operation. Consider the enable/disable feature if power conservation is necessary during idle states. Verify compatibility with LVCMOS compatible inputs on the receiving digital logic to ensure signal integrity without additional level shifting components.
Part Context
This oscillator belongs to the Mercury Electronics SMD oscillator series, which includes various frequencies and packages. The 18QHTF21 series typically offers standard performance characteristics for general timing applications. Mercury Electronics specializes in quartz crystals and oscillators, providing frequency control solutions for diverse electronic industries.
Replacement Considerations
Direct substitutes include other 105.63 MHz LVCMOS oscillators in 4-SMD packages from Mercury Electronics or other manufacturers. Ensure replacement parts match the 1.8V supply requirement and pinout configuration. Verify that the replacement maintains similar frequency stability and phase noise specifications for critical timing applications.
