Overview

The 8V41N004I is a clock generator designed for Gigabit Ethernet, 10 Gigabit Ethernet, SGMII, and PCI Express applications. The device generates a selectable 100MHz, 125MHz, 156.25MHz, or 312.5MHz clock signal from a 25MHz input. The 8V41N004I uses Renesas' fourth generation FemtoClock® NG technology to provide low phase noise performance, combined with excellent power supply noise rejection for optimal performance in the targeted applications. The device supports a 3.3V supply voltage and is packaged in a compact, lead-free (RoHS 6) 32-lead VFQFN package. The industrial temperature range supports high-end computing, telecommunication, and networking end equipment requirements.
