8T49N205A-004NLGI

Overview

The 8T49N205A-004NLGI is a FemtoClock NG frequency translator IC manufactured by Renesas Electronics. It operates with a single supply voltage ranging from 2.375V to 3.465V and supports input formats including HCSL, LVDS, and LVPECL. The device provides one output channel configured for LVPECL signaling. It is housed in a 40-VFQFN exposed pad package and is rated for an operating temperature range of -40°C to +85°C.

Feature Summary

• Supports flexible input signal formats including HCSL, LVDS, and LVPECL
• Generates low phase noise LVPECL output signals
• Operates within a standard industrial temperature range

Applications

• High-speed data communication systems
• Networking equipment clock distribution
• Test and measurement instrumentation

Procurement Notes

Verify the specific suffix '004' against official Renesas documentation to confirm pinout and electrical characteristics. Confirm package type matches design requirements. Check current availability status as clock synthesizers may have limited stock or end-of-life notices. Ensure ESD protection protocols are followed during handling.

Selection Notes

Select this component when a single LVPECL output is required from mixed-format inputs. Compare phase noise specifications against system jitter budgets. Verify voltage compatibility with existing power rails. Consider package thermal performance for dense PCB layouts.

Part Context

This part belongs to the FemtoClock NG family, designed for low-jitter clock generation and translation. It serves as a bridge between different logic families in high-performance digital systems. The series emphasizes signal integrity and flexibility for complex timing architectures.
