8T49N004A-067NLGI

Overview

The 8T49N004A-067NLGI is a clock generator from the FemtoClock NG series by Renesas Electronics Corporation. It operates at a maximum frequency of 156.25MHz with one circuit and a 1:4 input-to-output ratio. The device features differential LVPECL outputs and accepts crystal inputs. It functions within a supply voltage range of 2.375V to 3.465V and supports an operating temperature range of -40°C to 85°C. The component is housed in a 32-VFQFN exposed pad package, specifically a 32-VFQFN (5x5) supplier device package.

Feature Summary

• Generates low-jitter clock signals using the FemtoClock NG technology for high-performance timing applications.
• Provides four differential LVPECL output channels derived from a single input source.
• Utilizes a compact 32-VFQFN surface-mount package with an exposed pad for thermal optimization.

Applications

• High-speed data communication systems requiring precise clock distribution
• Telecommunications infrastructure equipment
• Server and storage backplane timing solutions

Procurement Notes

Verify the specific suffix '067' against the official Renesas ordering guide to confirm the exact output frequency and pinout configuration. Check the product status as this component may be subject to discontinuation notices or production changes. Ensure compatibility with the required supply voltage and temperature range for the target application environment before finalizing procurement.

Selection Notes

Select this model when a 156.25MHz clock signal with differential LVPECL outputs is required. Consider the 32-VFQFN package size for board space constraints. Verify that the input crystal frequency matches the internal PLL requirements. Compare against other FemtoClock NG variants if different output ratios or voltage levels are needed.

Part Context

This part belongs to the Renesas FemtoClock NG family, designed for ultra-low jitter performance. It is related to other models like the 8T49N004A-066NLGI8 and 8T49N004A-064NLGI, which share similar packaging but differ in frequency specifications and output types. The series is widely used in networking and computing applications demanding high signal integrity.

Replacement Considerations

Consult the official Renesas replacement guide for direct substitutes. Cross-reference with IDT8T49N004A-067NLGI for equivalent specifications. Verify pin-to-pin compatibility and electrical parameters before substituting with other clock generators in the same package type.
