Procurement Notes

Verify the specific output frequency variant (161.1328 MHz or 174.7031 MHz) required for your design, as this part number may correspond to a specific frequency option within the series. Confirm that the LVPECL output format aligns with your receiver input requirements. Ensure the 7 mm x 5 mm footprint matches your PCB layout constraints. Check the latest datasheet for any pin configuration details or enable pin specifications if applicable to your system design.

Selection Notes

Select this component when a fixed-frequency LVPECL clock source is needed for high-speed interfaces like PCIe or Ethernet. Compare against other Si512 variants if different frequencies or output formats are required. Consider the 25 PPM stability requirement against your system's jitter tolerance. Evaluate the 3.3 V supply compatibility with your power rails. Verify thermal management needs given the operating temperature range and power consumption characteristics.
