8T49N222B-123NLGI

Overview

The 8T49N222B-123NLGI is a FemtoClock NG programmable clock generator manufactured by Renesas Electronics. It operates within a supply voltage range of 2.375V to 3.465V and supports a maximum frequency of 1GHz. The device features one circuit with an input-to-output ratio of 3:2, supporting differential inputs and outputs. Input formats include HCSL, LVDS, LVHSTL, LVPECL, and crystals, while the output format is LVDS. It is housed in a 48-VFQFN package with an exposed pad and functions reliably across a temperature range of -40°C to 85°C.

Feature Summary

• Supports multiple input formats including HCSL, LVDS, LVHSTL, LVPECL, and crystals.
• Generates LVDS outputs with a 3:2 input-to-output frequency ratio.
• Capable of operating at frequencies up to 1GHz.
• Available in a compact 48-VFQFN (7x7) package with an exposed pad.

Applications

• High-speed serial link clock generation

Procurement Notes

Verify the specific suffix '123' against official Renesas documentation to confirm exact configuration parameters, as ordering suffixes define internal settings. Confirm current production status and availability through authorized distributors, as lead times may vary based on manufacturing schedules.

Selection Notes

Select this component when a single LVDS output derived from a 3:2 division of a high-frequency input is required. Ensure the design accommodates the 2.375V to 3.465V supply voltage range and the thermal requirements of the 48-VFQFN package for the intended operating environment.

Part Context

This part belongs to the FemtoClock NG series, designed for low-jitter clock generation and translation. It serves as a specialized solution for applications requiring precise frequency synthesis and signal format conversion between various logic families.

Replacement Considerations

Consult the Renesas FemtoClock NG selection guide for compatible alternatives. Verify pinout compatibility and electrical specifications before substituting with other models in the 8T49N222 family or related series.
