NBSG11MNR2G

Clock Buffers, Drivers Overview

The NBSG11MNR2G is a 1-to-2 differential fanout buffer manufactured by onsemi, designed for low skew and ultra-low jitter applications. It accepts inputs from Negative ECL (NECL), Positive ECL (PECL), CML, LVCMOS, LVTTL, or LVDS signals. The device features Reduced Swing ECL (RSECL) outputs with a 400 mV peak-to-peak amplitude. It incorporates internal 50 Ω termination resistors at the input pins. The maximum input clock frequency reaches 12 GHz typical, with a propagation delay of 125 ps typical. It operates within a supply voltage range of 2.375 V to 3.465 V for VCC or -2.375 V to -3.465 V for VEE, housed in a QFN-16 package.
