Oscillators Procurement Notes

Verify the specific suffix TJHPA0 matches the required reel packaging configuration. Confirm that the enable/disable pinout aligns with the system design requirements. Ensure the 4-SMD footprint dimensions are compatible with the PCB layout constraints. Validate that the supply voltage range covers the target operating conditions.

Oscillators Selection Notes

Select this model when a 39.864 MHz CMOS output is required with industrial temperature ratings. Consider the enable/disable feature if power management during idle states is necessary. Compare against other SG-8018 series variants if different frequencies or package sizes are needed. Ensure the ±50 ppm stability meets the system jitter specifications.

Oscillators Part Context

This component belongs to the SG-8018 series of standard oscillators from Epson Timing. The series offers various frequencies and package options for general-purpose clocking applications. The CB variant specifically denotes the package type and performance characteristics within the lineup. It serves as a direct replacement for legacy oscillators requiring similar form factors.

Oscillators Replacement Considerations

Direct substitutes include other SG-8018CB models with identical frequency and package but different suffixes for packaging variations. Cross-reference with Epson's official substitution guide for equivalent performance parts. Verify pin compatibility and electrical parameters before replacing with non-Epson components.
