8T49N203A-014NLGI8

Overview

The 8T49N203A-014NLGI8 is a Universal Frequency Translator from the FemtoClock NG series, manufactured by Renesas Electronics Corporation. It operates on a single supply voltage of 2.375V to 3.465V and supports a maximum frequency of 25MHz. The device features one circuit with differential input and output capabilities, accepting HCSL, LVDS, LVHSTL, LVPECL, or crystal inputs. Outputs are configured as LVPECL. It is housed in a 40-VFQFN package with an exposed pad (6x6mm) and functions within an operating temperature range of -40°C to 85°C.

Feature Summary

• Universal frequency translation with a 3:2 input-to-output ratio
• Supports multiple input levels including LVPECL, LVDS, HCSL, and crystals
• Low power operation with 2.375V to 3.465V supply range
• Integrated PLL with bypass capability for flexible clock generation

Applications

• Telecom infrastructure equipment requiring precise clock synthesis
• Data communication systems utilizing differential signaling standards
• Industrial control systems needing jitter attenuation
• Test and measurement instruments requiring stable frequency references

Procurement Notes

This component is marked as obsolete and no longer manufactured by Renesas Electronics Corporation. Verification of availability should focus on replacement part numbers such as the 8T49N241 series. Buyers must confirm end-of-life status and lead times through authorized distributors, as stock levels vary significantly across suppliers.

Selection Notes

Select this component only if the specific 25MHz maximum frequency and 3:2 ratio meet design requirements. Verify that the 40-VFQFN footprint is compatible with the PCB layout. Ensure the system can accommodate the 2.375V to 3.465V supply voltage. Due to obsolescence, evaluate alternative devices like the 8T49N241 series for long-term production viability.

Part Context

Part of the FemtoClock NG family, designed for high-performance clocking applications. This specific model serves as a universal frequency translator, bridging different clock domains in networking and telecom gear. It integrates jitter attenuation and frequency synthesis capabilities into a compact surface-mount package.

Replacement Considerations

The 8T49N241-994NLGI, 8T49N241-998NLGI, and 8T49N241-999NLGI are listed as available substitutes. These newer models offer similar functionality but may require firmware or register reconfiguration. Verify pin compatibility and electrical specifications before substitution.
