8T49N004A-070NLGI8

Overview

The 8T49N004A-070NLGI8 is a single-circuit clock generator from the FemtoClock NG series, manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 2.375V to 3.465V and supports an input-to-output ratio of 1:4. The device features differential LVPECL outputs and accepts HCSL, LVDS, or LVPECL inputs. It is housed in a 32-VFQFN package with an exposed pad, designed for surface mount installation. The component is rated for operation between -40°C and +85°C.

Feature Summary

• Single PLL circuit with 1:4 input-to-output frequency ratio
• Differential LVPECL output configuration
• Supports HCSL, LVDS, and LVPECL input levels
• Operates on 2.375V to 3.465V power supply

Applications

• High-speed data communication systems
• Networking equipment requiring precise clock distribution
• Industrial control systems with strict timing requirements

Procurement Notes

Verify the specific ordering suffix '070' against official Renesas documentation to confirm factory-programmed frequency configurations. Confirm current availability status as this product line may have discontinuation notices. Ensure compatibility with I2C programming interfaces if custom register settings are required beyond the default factory code.

Selection Notes

Select this component when a single differential LVPECL output fanout buffer with jitter attenuation is needed. Verify that the 32-VFQFN footprint matches the PCB layout constraints. Ensure the application environment stays within the specified -40°C to +85°C temperature range and utilizes the correct 2.375V to 3.465V supply voltage.

Part Context

This part belongs to the FemtoClock NG family, which integrates low-phase noise frequency translation and jitter cleaning capabilities. The 8T49N004A variant specifically provides a 1:4 fanout structure. Related parts in the series include the 8T49N004A-058NLGI8 and 8T49N004A-002NLGI, which share similar packaging but differ in maximum frequency specifications and internal configurations.
