Description

The NBSG11 is a 1−to−2 differential fanout buffer, optimized for low skew and Ultra−Low JITTER.

Inputs incorporate internal 50Ω termination resistors and accept Negative ECL (NECL), Positive ECL (PECL), CML, LVCMOS, LVTTL, or LVDS. Outputs are Reduced Swing ECL (RSECL), 400 mV. All outputs loaded with 50Ω to VCC − 2 V.
