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 4-SMD footprint matches your PCB layout constraints. Cross-reference the datasheet for operating temperature range limits to guarantee reliability under your intended environmental conditions.

Selection Notes

Select this component when a precise 61.38 MHz reference is required with low power consumption capabilities. The integrated enable pin allows for dynamic power saving during idle states. Consider the small form factor if space is limited on the printed circuit board. Verify compatibility with downstream logic inputs accepting LVCMOS signals.
