Crystals Procurement Notes

Verify the specific suffix 'BBK' against the manufacturer's current datasheet to confirm package dimensions and termination type, as variations exist within the 9C series. Confirm RoHS compliance status directly with the supplier documentation. Check lifecycle status as some listings indicate obsolete status, requiring validation of long-term availability before integration into new designs.

Crystals Selection Notes

Select this component when a 3.579545 MHz reference is required for NTSC video or specific communication protocols. Ensure the PCB layout accommodates the HC-49/S SMD form factor. Verify that the circuit load capacitance matches the specified 20 pF to maintain frequency accuracy within the ±50 ppm tolerance limits.

Crystals Part Context

This part belongs to the 9C series of surface-mount crystals from TXC Corporation. These components are designed to replace through-hole HC-49/U units in space-constrained applications while maintaining similar electrical characteristics. The series offers various frequency options tailored for standard clocking requirements.

Crystals Replacement Considerations

Direct substitutes include other manufacturers' HC-49/S SMD crystals at 3.579545 MHz with matching 20 pF load capacitance and ±50 ppm stability. Cross-reference part numbers such as those from Epson or NDK that specify identical package dimensions and electrical parameters.
