The 83905I is a low skew, 1-to-6 LVCMOS / LVTTL Fanout Buffer and a member of the  family of High Performance Clock Solutions from IDT. The low impedance LVCMOS/LVTTL outputs are designed to drive 50Ω series or parallel terminated transmission lines. The effective fanout can be increased from 6 to 12 by utilizing the ability of the outputs to drive two series terminated lines. The 83905I is characterized at full 3.3V, 2.5V, and 1.8V, mixed 3.3V/2.5V, 3.3V/1.8V and 2.5V/1.8V output operating supply mode. Guaranteed output and part-to-part skew characteristics along with the 1.8V output capabilities makes the 83905I ideal for high performance, single ended applications that also require a limited output voltage.
