8T49N004A-056NLGI8

Overview

The 8T49N004A-056NLGI8 is a clock generator from the FemtoClock NG series manufactured by Renesas Electronics. It features a single circuit with a 1:4 input-to-output ratio, converting crystal inputs to LVDS outputs. The maximum output frequency is 312.5MHz. It operates on a supply voltage of 2.375V to 3.465V and supports an operating temperature range of -40°C to 85°C. The device is housed in a 32-VFQFN package with an exposed pad.

Feature Summary

• Single circuit configuration with 1:4 input-to-output ratio
• Maximum output frequency of 312.5MHz
• LVDS differential output signaling
• Crystal input interface

Applications

• General clock generation for digital systems requiring low jitter
• Data communication equipment clock distribution
• Industrial control system timing references

Procurement Notes

This component is listed as obsolete by the manufacturer. Verification of availability should focus on distributor stock or last-time buy notices. Ensure the ordering suffix matches the required package and temperature grade. Confirm RoHS3 compliance status before procurement.

Selection Notes

Select this part when a single PLL with four LVDS outputs at frequencies up to 312.5MHz is required. Verify that the 32-VFQFN package fits the PCB layout constraints. Check if the crystal input requirement aligns with the system reference design. Compare against other FemtoClock NG variants if different output counts or voltage levels are needed.

Part Context

Part of the FemtoClock NG family, which integrates fourth-generation PLL technology for low phase noise performance. This specific model focuses on simple frequency translation from a crystal source to multiple LVDS clocks, differing from more complex universal frequency translators with multiple PLLs.

Replacement Considerations

As the part is obsolete, check for direct replacements within the 8T49N004 series with updated suffixes. Consider equivalent devices from SiTime following the acquisition of Renesas' timing product portfolio. Verify pin compatibility and electrical specifications before substitution.
