Oscillators Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm that the specific part number matches the required specifications, as this item is listed as obsolete or discontinued in several major distribution networks. Ensure compatibility with existing PCB footprints and verify RoHS compliance status prior to integration into new designs.

Oscillators Selection Notes

Consider alternative MEMS oscillators from the same manufacturer if availability is critical due to the obsolete status. Evaluate power consumption requirements against the 25 mA maximum draw. Ensure the 3.2 mm x 2.5 mm footprint fits within the design constraints. Compare frequency stability and temperature range against application needs to determine if this specific model remains suitable or if a newer generation part is preferred.

Oscillators Part Context

This component belongs to the broader category of MEMS oscillators produced by TXC Corporation. It serves as a replacement for traditional quartz crystals in applications demanding smaller form factors and greater shock resistance. The series includes various frequencies and packages, but this specific model is defined by its 19.44 MHz output and compact SMD housing.
