8V41N004I数据手册Renesas中文资料规格书

描述 Description

The IDT8V41N004I 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 25MHz input. The IDT8V41N004I uses IDT’s 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.
