Crystals Procurement Notes

Verify the specific ordering suffix to ensure the correct tolerance and package variant matches the design requirements. Confirm that the 10 pF load capacitance aligns with the host circuit's specifications. Check for RoHS compliance documentation if required for regulatory standards. Ensure the 40 Ohm maximum series resistance is acceptable for the application's drive level constraints.

Crystals Selection Notes

Select this component when a 54 MHz reference with ±10 ppm accuracy is required in a small surface-mount form factor. Consider the 10 pF load capacitance requirement for proper frequency matching with the oscillator circuit. Evaluate the 40 Ohm impedance against the driver capability of the target system. Verify thermal stability needs as standard crystals may have temperature-dependent variations outside specified ranges.

Crystals Part Context

This part belongs to CTS-Frequency Controls' line of surface-mount crystal oscillators. These components are designed to replace through-hole or larger package alternatives in modern PCB layouts. The 435 series typically offers high reliability and consistent performance across production batches, supporting mass manufacturing processes.

Crystals Replacement Considerations

Direct substitutes must match the 54 MHz frequency, ±10 ppm tolerance, 10 pF load capacitance, and 5.0x3.2mm SMD package. Verify pin compatibility and electrical parameters before substitution. Cross-reference with other manufacturers offering equivalent surface-mount crystals.
