Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct voltage and output type configuration. Confirm that the lead-free status aligns with environmental compliance requirements for your manufacturing process. Cross-reference the package outline drawing with your PCB footprint library to guarantee mechanical compatibility during assembly.

Selection Notes

Select this component when a precise 65.535 MHz reference is required for LVCMOS-compatible circuits. Ensure the 1.8V supply voltage matches the target system's power rail. Consider the small 2.0x1.6 mm footprint if space constraints are critical. Validate that the enable pin requirement fits the system's power sequencing strategy before finalizing the bill of materials.
