Procurement Notes

Verify the specific suffix 'T' indicates the tape-and-reel packaging variant when ordering. Confirm that the required output format matches the LVPECL specification provided in the datasheet. Ensure the system power supply remains within the 2.375V to 3.465V operating range to maintain proper functionality. Cross-reference the pinout against the 8-TSSOP footprint to avoid assembly errors during integration.

Selection Notes

Select this component when a fixed 160MHz clock source is required for Ethernet PHY connections. The LVPECL output is suitable for low-noise applications demanding high signal quality. Consider the 8-TSSOP package size if board space is limited compared to larger packages. Verify compatibility with the host system's voltage levels before implementation.
