8T49N004A-045NLGI8

Overview

The 8T49N004A-045NLGI8 is a clock generator from the FemtoClock NG series manufactured by Renesas Electronics Corporation. It features a single circuit with a 1:4 input-to-output ratio and supports differential inputs and outputs. The device operates on a supply voltage of 2.375V to 3.465V and supports maximum frequencies up to 300MHz. It utilizes LVPECL, LVDS, or HCSL input levels and provides LVPECL outputs. The component is housed in a 32-VFQFN package with an exposed pad and functions within an ambient temperature range of -40°C to 85°C.

Procurement Notes

Verify the specific ordering suffix '045' against official Renesas documentation to confirm the exact factory pre-programmed frequency configuration. Confirm current availability status as this product family may have end-of-life notices. Ensure compatibility with the required 32-VFQFN footprint during procurement planning.

Selection Notes

Select this component when a single PLL with four LVPECL outputs is required for frequencies up to 300MHz. Verify that the input signal matches the supported LVPECL, LVDS, or HCSL standards. Ensure the design accommodates the 32-VFQFN package thermal requirements and the specified 2.375V to 3.465V power supply constraints.

Part Context

This part belongs to the FemtoClock NG family, which integrates fourth-generation PLL technology for low phase noise applications. The base model 8T49N004 serves as a fundamental building block for clock distribution networks. The specific suffix determines the internal register settings for frequency synthesis.

Replacement Considerations

Check for direct substitutes within the 8T49N004A series with different frequency configurations. Verify pinout compatibility with the 32-VFQFN package before considering alternative vendors.
