Crystals Procurement Notes

Verify the specific ordering suffix and package variant against the official TXC Corporation datasheet to ensure compatibility with design requirements. Confirm that the 20 pF load capacitance matches the oscillator circuit specifications. Check for RoHS compliance status and AEC-Q200 qualification if automotive standards are required for the application.

Crystals Selection Notes

Select this component when a 28.63636 MHz fundamental frequency is required with a 20 pF load capacitance. Ensure the PCB layout accommodates the 3.2 mm x 2.5 mm SMD footprint. Consider the 80 Ohm ESR value for oscillator circuit design to guarantee reliable startup. Verify thermal constraints allow for the specified 150°C maximum operating temperature.

Crystals Part Context

This part belongs to the AM series of quartz crystals from TXC Corporation. It is a fundamental mode crystal resonator intended for general-purpose timing applications. The component is distinct from other TXC series such as AV or AA, which may feature different load capacitances or automotive certifications.

Crystals Replacement Considerations

The 7M-28.63636MAAE-T is listed as a similar alternative by distributors. However, it specifies a 12 pF load capacitance, which differs from the 20 pF requirement of the AM-28.63636MAGK-T. Direct substitution requires verification of oscillator circuit compatibility with the differing load capacitance.
