NBSG11BAHTBG

Clock Buffers, Drivers Overview

The NBSG11BAHTBG is a 2.5V/3.3V SiGe 1-to-2 differential fanout buffer manufactured by onsemi, designed for low skew and ultra-low jitter applications. It features internal 50Ω input termination resistors and accepts Negative ECL (NECL), Positive ECL (PECL), CML, LVCMOS, LVTTL, or LVDS inputs. The outputs are Reduced Swing ECL (RSECL) with a 400 mV peak-to-peak amplitude, typically loaded with 50Ω to VCC − 2 V. Operating at maximum clock frequencies up to 12 GHz typical, the device provides a propagation delay of 125 ps typical and rise/fall times of 30 ps typical.
