8T49N004A-059NLGI8

Overview

The 8T49N004A-059NLGI8 is a FemtoClock NG programmable clock generator manufactured by Renesas Electronics. It features one circuit with a maximum frequency of 300MHz and supports a 1:4 input-to-output ratio. The device utilizes LVPECL outputs and accepts HCSL, LVDS, or LVPECL inputs. It operates within a supply voltage range of 2.375V to 3.465V and functions at temperatures between -40°C and +85°C. The component is housed in a 32-VFQFN package with an exposed pad.

Feature Summary

• Integrates a PLL with bypass functionality for flexible clock signal management
• Supports multiple differential input formats including HCSL, LVDS, and LVPECL
• Delivers four differential LVPECL output signals

Applications

• High-performance computing systems requiring precise clock distribution
• Telecommunications infrastructure equipment
• Data center networking hardware

Procurement Notes

Verify the specific ordering suffix to confirm pinout and electrical characteristics match design requirements. Confirm RoHS3 compliance status and moisture sensitivity level (MSL 3) for surface mount assembly processes. Check current production status as availability may vary due to lifecycle changes.

Selection Notes

Select this component when a single-input, four-output clock generation solution is required. Ensure the application supports the specified 2.375V to 3.465V supply range. Verify that the 32-VFQFN package dimensions fit the PCB layout constraints and thermal requirements.

Part Context

This part belongs to the FemtoClock NG series, designed for low-jitter clock synthesis. It serves as a replacement for legacy IDT clock generators. The device integrates EEPROM for configuration storage, allowing for customized frequency settings without external components.

Replacement Considerations

IDT8T49N004A-058NLGI8 is a confirmed substitute part number within the same family.
