8T33FS6221EPGI8

Clock Buffers, Drivers Overview

The 8T33FS6221EPGI8 is a high-performance clock fanout buffer manufactured by Renesas Electronics. It provides a 1:20 distribution ratio, accepting differential HSTL or PECL inputs and generating twenty differential PECL outputs. The device supports maximum frequencies up to 2 GHz with a supply voltage range of 2.375V to 2.625V or 3.135V to 3.465V. Packaged in a 52-PTQFP (10x10 mm) surface-mount case with an exposed pad, it operates within a temperature range of -40°C to 85°C.
