8T49N222B-127NLGI

Overview

The 8T49N222B-127NLGI is a Universal Frequency Translator from the FemtoClock NG series, manufactured by Renesas Electronics. It operates on a single 2.375V to 3.465V supply and features one circuit with a 3:2 input-to-output ratio. The device supports HCSL, LVDS, LVHSTL, LVPECL, or crystal inputs and provides LVDS outputs. It achieves a maximum frequency of 1GHz within an operating temperature range of -40°C to 85°C. The component is housed in a 48-VFQFPN (7x7) package.

Feature Summary

• Supports multiple input formats including HCSL, LVDS, LVHSTL, LVPECL, and crystals
• Provides differential LVDS output signals
• Integrates a bypassable PLL for frequency translation

Applications

• High-speed data communication systems
• Test and measurement equipment
• Industrial networking infrastructure

Procurement Notes

Verify the specific suffix 'NLGI' against official Renesas documentation to confirm the exact pinout, thermal pad configuration, and tape-and-reel specifications. Ensure the source document explicitly lists this part number as active or available, as distribution channels may list obsolete status for similar variants. Cross-reference the voltage and temperature ratings with your system requirements before ordering.

Selection Notes

Select this component when a precise 3:2 frequency division or multiplication is required with low jitter performance. It is suitable for designs needing flexible input compatibility across standard logic families. Consider the 48-pin package size for board space constraints. Verify that the 1GHz maximum frequency meets the target signal speed requirements.
