8T49N008A-016NLGI

Overview

The 8T49N008A-016NLGI is a programmable FemtoClock NG clock generator manufactured by Renesas Electronics. It features an integrated crystal oscillator and provides eight selectable LVPECL or LVDS outputs. The device utilizes fourth-generation FemtoClock NG PLL technology with a VCO range of 1.92GHz to 2.5GHz. It supports I2C programming for register configuration and is designed to meet jitter compliance standards for PCI Express Gen2 (5Gb/s) and Gen3 (8Gb/s). The component operates within an ambient temperature range of -40°C to +85°C.
