Crystals Procurement Notes

Verify the specific suffix 'R' against the manufacturer's official documentation to confirm reel packaging specifications and tape-and-reel compatibility. Ensure the load capacitance requirement matches the oscillator circuit design. Confirm RoHS compliance status through the latest datasheet revision. Cross-reference the ESR value with the host circuit's drive level constraints to prevent over-driving the crystal element.

Crystals Selection Notes

Select this component when a 38.4 MHz reference is required for space-constrained designs utilizing SMD footprints. The 12 pF load capacitance must align with the oscillator circuit's total stray capacitance. Consider the ±15 ppm tolerance for applications requiring moderate frequency accuracy. Evaluate the 70 Ohm ESR against the oscillator amplifier's capability to sustain oscillation reliably under all environmental conditions.

Crystals Part Context

This part belongs to the C2E series of surface-mount crystals from Aker Technology Corp. The series offers various frequencies and packages optimized for compact electronic assemblies. The C2E designation indicates a specific footprint and mounting style distinct from other AKER crystal families. This model represents a standard commercial-grade solution for general-purpose timing applications.

Crystals Replacement Considerations

Direct substitutes include the C2E-38.400-12-1520-M variant, which shares identical electrical parameters but may differ in packaging configuration. Verify pinout compatibility and mechanical dimensions before substitution. Other manufacturers offering 38.4 MHz crystals in 3225 packages require careful validation of ESR and load capacitance matching.
