Oscillators Procurement Notes

Verify the specific suffix codes against official manufacturer documentation to ensure correct voltage and output specifications. Confirm that the required operating temperature range aligns with the -20°C to +70°C rating. Check for RoHS compliance status if environmental regulations apply to your project. Ensure the 6-SMD footprint matches your PCB design constraints before finalizing procurement.

Oscillators Selection Notes

Select this component when an HCSL output is required for high-speed data transmission compatibility. Consider the ±30 ppm stability for applications tolerant of moderate frequency drift. Evaluate the 2.5V supply requirement against available power rails. Compare physical dimensions against space-constrained designs to ensure fitment within the 5.00mm x 3.20mm envelope.

Oscillators Part Context

This part belongs to the 645H series of HCSL clock oscillators from CTS-Frequency Controls. These devices are engineered for demanding electronic applications requiring low-jitter clock signals. The series offers various frequencies and packaging options to suit different board layout requirements while maintaining consistent performance characteristics across the product line.

Oscillators Replacement Considerations

Direct substitutes must match the 25 MHz frequency, HCSL output type, and 6-SMD package dimensions. Verify equivalent supply voltage and enable/disable functionality. Cross-reference stability ratings to ensure comparable timing accuracy. Consult manufacturer cross-reference lists for validated alternative part numbers.
