8T49N004A-050NLGI

Overview

The 8T49N004A-050NLGI is a programmable clock generator from the FemtoClock NG series by Renesas Electronics. It features one circuit with a maximum frequency of 300MHz and a 1:4 input-to-output ratio. The device accepts differential inputs in HCSL, LVDS, or LVPECL formats and provides four LVPECL outputs. It operates on a supply voltage between 2.375V and 3.465V within an ambient temperature range of -40°C to 85°C. The component is housed in a 32-VFQFN package with an exposed pad.

Feature Summary

• Supports multiple differential input levels including HCSL, LVDS, and LVPECL
• Generates four selectable LVPECL output channels
• Utilizes fourth-generation FemtoClock NG PLL technology for low jitter performance

Applications

• High-speed data communication systems
• Network infrastructure equipment
• Test and measurement instruments

Procurement Notes

Verify the specific suffix '050' against official Renesas documentation to confirm the exact factory-programmed frequency configuration. Confirm current availability status as this product line may have discontinuation notices. Ensure compatibility with required I2C programming interfaces and power supply specifications during integration.

Selection Notes

Select this component when four independent LVPECL outputs are required from a single reference source. Verify that the input signal matches supported differential standards. Consider thermal management requirements for the VFQFN package. Check if alternative pin-compatible devices are available if this specific order code is discontinued.

Part Context

This part belongs to the FemtoClock NG family, designed for ultra-low jitter applications. It integrates a phase-locked loop with programmable dividers to generate precise clock signals. The device supports I2C configuration for flexible deployment in various digital systems requiring stable timing references.

Replacement Considerations

Consult official substitution guides for compatible FemtoClock NG variants. Verify electrical parameters and pinout compatibility before replacing. Check for updated ordering codes if the original part is obsolete.
