8T49N006A-056NLGI8

Overview

The 8T49N006A-056NLGI8 is a programmable clock generator from the FemtoClock NG series by Renesas Electronics. It features four selectable LVPECL or LVDS outputs and accepts differential inputs such as LVPECL, LVDS, or HCSL. The device utilizes fourth-generation PLL technology with a VCO range of 1.9 GHz to 2.55 GHz. It operates on a full 2.5V or 3.3V supply and supports I²C programming. The component is housed in a 32-VFQFN package with an exposed pad and functions within an ambient temperature range of -40°C to 85°C.

Feature Summary

• Generates low RMS phase jitter clock signals using fourth-generation FemtoClock NG PLL technology
• Provides four output channels configurable as either LVPECL or LVDS levels
• Supports flexible input configurations including crystal, LVPECL, LVDS, and HCSL sources
• Enables register programming via a standard I²C serial interface

Applications

• PCI Express compliant systems requiring jitter attenuation
• High-speed data transmission equipment
• Network synchronization hardware
• Test and measurement instrumentation

Procurement Notes

Verify the specific ordering suffix against official Renesas documentation to confirm voltage, package, and pre-programmed frequency settings. Confirm current availability status as components may be subject to discontinuation notices. Ensure compatibility with required input reference frequencies and output load conditions before integration into final designs.

Selection Notes

Select this component when low phase noise performance is critical for high-speed digital interfaces. The device is suitable for applications requiring multiple independent output frequencies derived from a single reference source. Consider the available output drive strength and power supply requirements relative to the system architecture constraints.

Part Context

This part belongs to the FemtoClock NG family, designed for ultra-low jitter clock generation. It serves as a direct replacement or upgrade for legacy clock synthesizers in high-performance computing and telecommunications infrastructure where signal integrity is paramount.

Replacement Considerations

Consult official substitution guides for compatible alternatives within the FemtoClock NG lineup. Verify pinout and electrical parameter equivalence before swapping with other models.
