Procurement Notes

This part number is listed as discontinued (EOL) by the manufacturer. Availability is limited to existing stock or surplus markets. Verify end-of-life notifications and last-time-buy dates before procurement planning. Alternative components from the same family may require design review.

Selection Notes

Select this component when eight differential LVPECL/LVDS outputs are required with FemtoClock NG jitter attenuation. Ensure input frequency ranges match the specific order code configuration. Check compatibility with system voltage levels and I2C bus requirements. Consider pin-out compatibility if replacing older variants in the 8T49N008 series.

Part Context

The 8T49N008A belongs to the FemtoClock NG family, which integrates low-phase noise frequency translation and jitter cleaning. This specific variant provides eight outputs configured for high-speed serial interfaces. It differs from other family members by its fixed output count and specific factory pre-programmed frequency sets defined by the suffix.

Replacement Considerations

Direct replacements include other 8T49N008 series variants with compatible pinouts and electrical characteristics. Verify that alternative parts support the same output voltage levels (LVPECL/LVDS) and package type. Cross-reference register maps if reprogramming is required.
