Procurement Notes
Verify the specific datasheet revision and electrical characteristics against the manufacturer's current documentation before integration. Confirm that the 4-SMD no-lead package dimensions align with the target PCB footprint. Ensure the enable/disable pin configuration matches the system control logic requirements. Validate supply chain authenticity through authorized distributors to guarantee component reliability and performance consistency.
Selection Notes
Select this oscillator when a fixed 20 MHz frequency is required with CMOS or TTL compatible outputs. Consider the enable/disable feature if power conservation or signal gating is necessary during idle states. Evaluate the leadless SMD package suitability for high-density board layouts. Compare thermal and electrical specifications against application constraints to ensure long-term stability and operational integrity.
