8T49N281C-998NLGI8

Overview

The 8T49N281C-998NLGI8 is a clock translator from the FemtoClock family manufactured by Renesas Electronics. It features eight differential outputs capable of reaching a maximum frequency of 1 GHz, derived from a maximum input frequency of 40 MHz. The device operates on a single power supply ranging from 2.375 V to 3.465 V and supports output levels including LVPECL, LVDS, and LVCMOS. Packaged in a 56-pin VFQFN with an exposed pad, it is designed for high-performance timing applications requiring precise frequency translation.

Feature Summary

• Eight configurable differential outputs (LVPECL, LVDS, LVCMOS) supporting frequencies up to 1 GHz
• Input frequency range limited to a maximum of 40 MHz
• Low phase jitter performance with typical values between 300 fs and 313 fs
• Single voltage supply operation from 2.375 V to 3.465 V

Applications

• High-speed data communication equipment
• Network synchronization systems
• Test and measurement instrumentation

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS3 compliance status and check for relevant PCNs regarding assembly site changes or material updates prior to procurement.

Selection Notes

Select this model when an input reference frequency does not exceed 40 MHz but requires translation to higher output frequencies up to 1 GHz. Ensure the design accommodates the 56-VFQFN package dimensions and thermal requirements associated with the exposed pad.

Part Context

This part belongs to the FemtoClock NG Universal Frequency Translator series. It shares architectural similarities with other models like the 8T49N241 and 8T49N242 but is distinguished by its specific 8-output configuration and lower maximum input frequency specification.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate alternative devices within the same FemtoClock family only if they match the specific 40 MHz input limit and 8-output requirement.
