8T49N004A-068NLGI8

Overview

The 8T49N004A-068NLGI8 is a FemtoClock NG clock generator IC manufactured by Renesas Electronics Corporation. It operates at a maximum frequency of 245.76MHz with a 1:4 input-to-output ratio. The device features differential LVPECL outputs and accepts crystal inputs. It is housed in a 32-VFQFN exposed pad package, measuring 5x5mm. The component supports a supply voltage range of 2.375V to 3.465V and functions within an operating temperature range of -40°C to 85°C.

Feature Summary

• Generates precise clock signals using the FemtoClock NG architecture for low jitter performance.
• Provides four differential LVPECL output channels derived from a single input source.

Applications

• High-speed data communication systems requiring precise clock distribution.
• Networking equipment utilizing LVPECL interface standards.
• Industrial control systems operating within specified temperature ranges.

Procurement Notes

Verify the specific suffix '068' against official Renesas documentation to confirm the exact frequency configuration and pinout compatibility. Confirm RoHS3 compliance status and check for any recent Product Change Notifications (PCNs) regarding assembly sites or labeling updates prior to procurement.

Selection Notes

Select this component when a 245.76MHz clock signal with differential LVPECL outputs is required. Ensure the design accommodates the 32-VFQFN thermal pad requirements and the 2.375V to 3.465V power supply constraints. Verify that the application environment remains within the -40°C to 85°C operational temperature limits.
