8T49N240-023NLGI

Overview

The Renesas 8T49N240-023NLGI is a FemtoClock NG Universal Frequency Translator. It features a single fractional-feedback PLL capable of jitter attenuation or frequency synthesis. The device generates up to four independent output frequencies ranging from 8 kHz to 1 GHz using integer output dividers. Outputs support LVPECL, LVDS, HCSL, and LVCMOS levels. Configuration is managed via I2C or external EEPROM. It supports hitless switching and phase-slope limiting for network line cards and baseband units.
