Procurement Notes
Verify the specific part number suffix against official manufacturer documentation to ensure correct frequency and package configuration. Confirm that the 1.8V supply requirement aligns with target system design constraints. Check for any lead-free compliance certifications required for the intended assembly process. Ensure the 4-SMD footprint matches the PCB layout specifications before ordering.
Selection Notes
Select this component when a 120.2367 MHz clock source is required for LVCMOS-compatible circuits. Consider the 1.8V operating voltage and small 2.0x1.6mm package size for space-constrained designs. Evaluate the enable/disable feature if dynamic power control is necessary. Verify temperature range requirements against the datasheet specifications for the target environment.
