8T49N203A-007NLGI8

Overview

The 8T49N203A-007NLGI8 is a Universal Frequency Translator from the FemtoClock NG series, manufactured by Renesas Electronics Corporation. It operates on a single supply voltage ranging from 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 ambient 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
• Differential LVPECL outputs for low jitter performance
• Integrated PLL with bypass capability

Applications

• Network synchronization equipment
• Telecommunications infrastructure
• Test and measurement instruments

Procurement Notes

This component is officially classified as obsolete and no longer manufactured by Renesas Electronics Corporation. Availability is limited to existing stock held by distributors. Verification of authenticity and storage history is critical due to the end-of-life status. Buyers should confirm the specific revision and packaging condition before acquisition.

Selection Notes

Designers requiring this specific frequency configuration must evaluate replacement options such as the 8T49N241 series. While functionally similar universal translators exist, pinouts and register configurations may differ. A thorough review of the updated datasheet and timing commander software compatibility is necessary to ensure seamless integration into existing designs.

Part Context

The 8T49N203A belongs to the FemtoClock NG family, known for low phase jitter performance. This specific part number represents a factory-programmed variant designed for fixed-frequency applications. The 'NLGI8' suffix indicates the lead-free RoHS-compliant packaging and tape-and-reel shipping format.

Replacement Considerations

Publicly confirmed substitute part numbers include 8T49N241-994NLGI, 8T49N241-998NLGI, and 8T49N241-999NLGI. These devices offer comparable functionality but require verification of electrical parameters and pin compatibility.
