IDT, Integrated Device Technology Inc 83948AYI-147LF

Description
The 839481147 is a low skew, 1to12 DifferentialtoLVCMOS/LVTTL Fanout Buffer. It has two selectable clock inputs: CLK/nCLK and LVCMOS CLK. The CLK/nCLK pair can accept most standard differential input levels, including LVPECL, LVDS, LVHSTL, SSTL, and HCSL. The LVCMOS CLK can accept LVCMOS or LVTTL input levels. The low impedance LVCMOS/LVTTL outputs are designed to drive 500 series or parallel terminated transmission lines. The effective fanout can be increased from 12 to 24 by utilizing the ability of the outputs to drive two series terminated lines.
