Oscillators Procurement Notes

Verify that the specific part number matches the required 27 MHz frequency and LVCMOS output logic levels. Confirm the package dimensions align with PCB layout constraints. Ensure the operating temperature range meets environmental requirements. Check for RoHS compliance documentation if necessary for regulatory standards. Validate supplier authenticity through authorized distribution channels.

Oscillators Selection Notes

Choose this oscillator when a 27 MHz clock source with ±20 ppm stability is required. Select based on the 3.3 V supply voltage compatibility and LVCMOS interface needs. Consider the 4-pin SMD package size for space-constrained designs. Evaluate the tri-state feature if system-wide clock gating is necessary. Compare against alternatives only if different frequency or voltage specifications are needed.

Oscillators Part Context

This component belongs to the EC36 series of standard clock oscillators from Ecliptek. The series offers various frequencies and packages, maintaining consistent electrical characteristics within model families. The EC3620 variant specifically denotes the 3.2mm x 5.0mm package size. This model represents a common choice for general-purpose digital timing applications.

Oscillators Replacement Considerations

Direct substitutes include other Ecliptek models with identical 27 MHz frequency, LVCMOS output, and ±20 ppm stability. Verify pinout compatibility and physical dimensions before substitution. Cross-reference with Abracon equivalents if available, ensuring electrical parameters match exactly.
