8T49N004A-064NLGI8

Overview

The 8T49N004A-064NLGI8 is a clock generator from the FemtoClock NG series by Renesas Electronics. It features a single PLL circuit with a 1:4 input-to-output ratio, supporting LVDS and LVPECL differential outputs. The device operates on a 2.375V to 3.465V supply within a -40°C to 85°C temperature range. It utilizes a crystal input and is housed in a 32-VFQFN exposed pad package (5x5 mm). This component is designed for low-jitter clock generation applications requiring precise frequency synthesis.

Procurement Notes

Verify the specific order code suffix against official Renesas documentation to confirm factory-programmed frequencies. Confirm RoHS3 compliance status and check for active production or obsolescence notices via manufacturer PCNs before procurement planning.

Selection Notes

Ensure the required output frequencies match the factory-programmed configuration for this specific part number. Verify that the system power supply remains within the 2.375V to 3.465V range. Confirm compatibility with the 32-VFQFN footprint and thermal requirements for the target application environment.

Part Context

This part belongs to the 8T49N004 family, which provides programmable clock generation solutions. The 'A' variant typically denotes specific feature revisions or enhanced performance characteristics compared to earlier generations within the FemtoClock NG portfolio.

Replacement Considerations

Check for direct pin-compatible substitutes within the 8T49N004 series with different frequency codes. Consider newer FemtoClock NG devices if updated packaging or extended temperature ranges are required.
