8T49N004A-047NLGI

Overview

The 8T49N004A-047NLGI is a FemtoClock NG clock generator manufactured by Renesas Electronics Corporation. It features a single PLL circuit with a 1:4 input-to-output ratio, supporting differential inputs and outputs. The device accepts HCSL, LVDS, or LVPECL input signals and generates LVPECL output signals. It operates within a supply voltage range of 2.375V to 3.465V and supports maximum frequencies up to 300MHz. The component is housed in a 32-VFQFN package with an exposed pad and functions reliably across a temperature range of -40°C to 85°C.
