Procurement Notes

Verify the specific voltage variant required, as the series supports 3.0 V, 3.3 V, and 5.0 V options. Confirm that the 50 MHz frequency matches the system clock requirements. Ensure the PCB footprint aligns with the 7.0 mm x 5.0 mm physical dimensions. Check for RoHS compliance status if environmental regulations apply to the final assembly. Validate the operating temperature range against the intended deployment environment.

Selection Notes

Select this component when precise timing is critical for wireless or avionics infrastructure. The HCMOS output simplifies interfacing with standard digital circuits without additional level shifting. The tri-state capability offers flexibility for system power-down modes. Consider the 1 ppm aging specification for long-term calibration needs. The wide supply voltage options allow integration into diverse power architectures.
