8T49N222B-110NLGI

Overview

The 8T49N222B-110NLGI is a FemtoClock NG Universal Frequency Translator manufactured by Renesas Electronics. It operates within a supply voltage range of 2.375V to 3.465V and supports an input frequency ratio of 3:2. The device features one circuit with differential input and output capabilities, supporting HCSL, LVDS, LVHSTL, and LVPECL input formats while providing LVDS outputs. It achieves a maximum frequency of 1GHz and is housed in a 48-VFQFN package with an exposed pad. The component functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Supports multiple input standards including HCSL, LVDS, LVHSTL, and LVPECL
• Provides LVDS differential outputs for low-noise signal transmission
• Integrated PLL with bypass capability for flexible clock management
• Capable of generating frequencies up to 1GHz with a 3:2 input-to-output ratio

Applications

• High-speed serial link clock generation
• Data converter timing synchronization
• Telecommunications infrastructure clocking
• Test and measurement equipment timing

Procurement Notes

Verify the specific suffix '110' against official Renesas documentation to confirm the exact frequency configuration and pinout compatibility. Ensure the 48-VFQFN package dimensions match the target PCB footprint. Confirm RoHS compliance status through the manufacturer's current datasheet before procurement.

Selection Notes

Select this component when a single-channel universal frequency translator with mixed-mode input support is required. The 3:2 ratio and 1GHz maximum frequency suit applications needing precise frequency translation from lower reference clocks. Verify that the LVDS output swing meets the receiver requirements of the downstream components.

Part Context

This part belongs to the FemtoClock NG family, designed for high-performance clock synthesis and jitter attenuation. The 8T49N222B variant specifically targets universal frequency translation tasks, offering flexibility in input/output format conversion compared to fixed-function clock generators.

Replacement Considerations

Check Renesas documentation for direct cross-references or updated revisions within the 8T49N222 series. Ensure any substitute maintains the 48-VFQFN package and electrical specifications for voltage and temperature ranges.
