8T79S308NLGI/W

Clock Buffers, Drivers Overview

The 8T79S308NLGI/W is a universal differential fanout buffer manufactured by Renesas Electronics. It provides a 1:8 output ratio, distributing a single differential input signal to eight differential outputs. The device supports LVDS and LVPECL input and output levels, operating at a maximum frequency of 3 GHz. It functions within supply voltage ranges of 1.71V to 1.89V, 2.375V to 2.625V, or 3.135V to 3.465V. Packaged in a 40-VFQFPN (6x6) exposed pad with Tape & Reel mounting, it is rated for an ambient operating temperature range of -40°C to 105°C.
