8T49N285-996NLGI

Overview

The 8T49N285-996NLGI is a clock synthesizer and jitter cleaner from Renesas Electronics, functioning as a universal frequency translator. It utilizes a fractional-feedback PLL to provide precise timing solutions. The device operates within a supply voltage range of 2.375V to 2.625V and 3.135V to 3.465V. It supports input formats including HCPL, LVCMOS, LVDS, LVHSTL, LVPECL, LVTTTL, and crystals. The output capabilities include HCPL, LVCMOS, LVDS, and LVPECL signals. It is housed in a 56-VFQFN exposed pad package with dimensions of 8x8 mm.

Feature Summary

• Integrates a fractional-feedback PLL for versatile jitter attenuation and frequency translation functions.
• Supports multiple differential and single-ended input/output signal standards for broad compatibility.
• Designed for high-performance timing applications requiring precise clock generation and synchronization.

Applications

• Jitter attenuation in high-speed data handling systems
• Port synchronization for complex digital interfaces
• Universal frequency translation for FPGA timing requirements

Procurement Notes

Verify the specific ordering suffix and package variant against the official Renesas datasheet to ensure compatibility with your design requirements. Confirm that the 56-VFQFN exposed pad footprint matches your PCB layout specifications. Check for any recent updates to the product status or recommended replacement parts before finalizing procurement plans.

Selection Notes

Select this component when a single IC must handle both jitter cleaning and frequency translation tasks. Ensure the required input and output voltage levels align with the supported ranges of 2.375V–2.625V and 3.135V–3.465V. Consider the thermal performance of the exposed pad package if operating in high-density environments.

Part Context

This part belongs to the FemtoClock NG series, designed for advanced timing applications. It serves as a key component in systems requiring low-jitter clock distribution. The series is known for its flexibility in supporting various input and output configurations across different industrial and communication sectors.

Replacement Considerations

Consult the official cross-reference list for direct substitutes. Verify pinout and electrical parameter compatibility before replacing. Generic alternatives may not support the same fractional-feedback PLL features or input/output standard combinations.
