8T49N004A-033NLGI8

Clock Generators, PLLs, Frequency Synthesizers Overview

The 8T49N004A-033NLGI8 is a programmable clock generator from the FemtoClock NG series by Renesas Electronics. It features one PLL with a 1:4 input-to-output ratio and supports differential inputs (HCSL, LVDS, LVPECL) to produce four LVPECL outputs. The maximum output frequency reaches 300MHz. Operating on a 2.375V to 3.465V supply, it is housed in a 32-VFQFN exposed pad package. The device operates within a temperature range of -40°C to 85°C.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

This component is officially marked as obsolete by the manufacturer. Production has ceased, and availability is limited to existing stock or last-time buy scenarios. Verify end-of-life status and lead times carefully before design-in.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this part for applications requiring low-jitter LVPECL generation from various differential input sources. Ensure the design accommodates the 32-VFQFN package thermal requirements and the specific 2.375V–3.465V voltage range.

Clock Generators, PLLs, Frequency Synthesizers Part Context

Part of the FemtoClock NG family, designed for jitter attenuation and frequency synthesis. This specific model focuses on single-input, four-output conversion, differing from multi-PLL variants like the 8T49N242 or 8T49N366I which offer more complex routing capabilities.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

As an obsolete part, direct substitutes are not guaranteed. Evaluate newer FemtoClock NG devices such as the 8T49N004A series revisions or other Renesas clock generators with compatible pinouts and electrical specifications.
