Oscillators Procurement Notes

Verify the specific suffix 'BD' against the manufacturer's official datasheet to confirm pinout configuration and enable signal polarity. Ensure that the selected variant matches the required operating temperature range and supply voltage specifications for the target application environment. Cross-reference the package dimensions with the PCB footprint library to guarantee mechanical compatibility during assembly.

Oscillators Selection Notes

Select this component when a stable 32.768 kHz reference is required with integrated power control capabilities. Consider the ±25 ppm stability specification against the system's timing accuracy requirements. Evaluate the 3.3V supply constraint relative to the host circuit's voltage levels. Confirm that the surface-mount form factor aligns with the manufacturing process and available board space constraints.

Oscillators Part Context

This oscillator belongs to the 7XZ series of ultra-small RTC oscillators from TXC Corporation. The series typically includes variants with different supply voltages, stability grades, and package types. The 7XZ-32.768KBD-T specifically denotes the 3.3V version with standard stability and no-lead packaging, distinguishing it from other series members like the 7WZ or 7XZ-32.768KCE-T which may have different electrical characteristics.

Oscillators Replacement Considerations

Direct substitutes include the 7XZ-32.768KDA-T, which offers similar performance but operates at 1.8V. For 3.3V applications requiring identical form factors, verify compatibility with other 7XZ series variants sharing the same package and frequency. Always validate electrical parameters and pin assignments before substitution.
