8T49N008A-066NLGI8

Overview

The Renesas 8T49N008A-066NLGI8 is a programmable clock generator from the FemtoClock NG series, manufactured by Renesas Electronics Corporation. It features a single PLL with one input and four outputs, supporting LVDS and LVPECL output types. The device operates on a 2.375V to 3.465V supply voltage and supports a maximum frequency of 245.76MHz. It is housed in a 32-VFQFN package with an exposed pad, designed for surface mount installation. The component functions as a clock synthesizer and jitter cleaner, utilizing I2C programming for register configuration.

Feature Summary

• Single PLL architecture with 1:4 input-to-output ratio
• Supports LVDS and LVPECL differential output levels
• Maximum output frequency of 245.76MHz
• Operates within a 2.375V to 3.465V voltage range

Applications

• High-speed data communication systems requiring low jitter clocks
• Networking equipment clock distribution
• Industrial control systems needing precise timing signals

Procurement Notes

This component is listed as discontinued (EOL) by the manufacturer. Verification of availability should focus on remaining stock or alternative sourcing channels. Check Product Change Notices (PCN) for any assembly site or labeling changes that may affect compatibility. Ensure compliance with RoHS3 standards before integration into new designs.

Selection Notes

Select this part when a single-input, four-output clock generator with LVDS/LVPECL outputs is required. Verify that the target application frequency does not exceed 245.76MHz. Confirm that the system power supply aligns with the 2.375V–3.465V operating range. Consider the 32-VFQFN package constraints for PCB layout and thermal management during selection.

Part Context

The 8T49N008A-066NLGI8 belongs to the FemtoClock NG family, known for fourth-generation PLL technology. This series integrates jitter attenuation and frequency synthesis capabilities. The specific suffix '066' denotes a factory-programmed frequency configuration. Other family members include variants with different output counts and frequencies, such as the 8T49N028 and 8T49N488I.

Replacement Considerations

As the part is discontinued, verify if the 8T49N008A-062NLGI or other 8T49N008A variants serve as functional substitutes. Cross-reference pinouts and electrical specifications carefully. Consult Renesas documentation for approved replacement strategies or last-time buy information.
