LTC6950IUHH

Clock Generators, PLLs, Frequency Synthesizers Overview

The LTC6950IUHH is a low noise, integer-N phase-locked loop (PLL) clock generator manufactured by Analog Devices. It features five independent output dividers capable of generating frequencies up to 1 GHz. The device operates on a single 3.3 V supply with a typical current consumption of 45 mA. It utilizes an I2C-compatible serial interface for configuration and includes an integrated charge pump. The component is housed in a compact 24-lead LQFP package and supports operation across an industrial temperature range of -40°C to +85°C.
