Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the system design specifications before procurement. Confirm that the 1.8V supply voltage aligns with the target circuit's power rails. Ensure the 4-SMD no-lead package footprint matches the PCB layout constraints to guarantee proper soldering and mechanical stability during assembly.

Selection Notes

Select this component when a precise 10.254 MHz timing source is required for LVCMOS-compatible digital logic. The choice is driven by the need for a low-profile surface-mount solution with integrated enable control capabilities. Consider the 1.8V operating voltage as a primary constraint for power-sensitive designs requiring minimal current consumption from the oscillator stage.
