5V49EE504NLGI8

Clock Generators, PLLs, Frequency Synthesizers Overview

The 5V49EE504NLGI8 is a VersaClock III programmable clock generator manufactured by Renesas Electronics. It features four internal Phase-Locked Loops (PLLs) and an integrated I2C EEPROM master interface for configuration storage. The device supports FAST mode I2C serial interfaces at 400kHz. It accepts input frequencies from TCXOs (10 MHz to 40 MHz) or crystals (8 MHz to 30 MHz). Output frequencies range from kHz to 120 MHz, with each PLL equipped with an 8-bit reference divider and an 11-bit feedback divider. One PLL supports spread spectrum generation configurable for pixel rates. The component operates within an industrial temperature range of -40°C to +85°C.
