The LVCMOS_CLK can accept LVCMOS or LVTTL input levels.
The low impedance LVCMOS/LVTTL outputs are designed to
drive 50
effective fanout can be increased from 8 to 16 by utilizing the
ability of the outputs to drive two series terminated trans-
mission lines.
The ICS8308I is characterized for 3.3V core/3.3V output,
3.3V core/2.5V output or 2.5V core/2.5V output operation.
Guaranteed output and part-part skew characteristics make
the 8308I ideal for those clock distribution applications requiring
well defined performance and repeatability.

The ICS8308I is a low-skew, 1-to-8 Fanout Buffer
and a member of the
Perfor mance Clock Solutions from IDT. The
ICS8308I has two selectable clock inputs. The CLK,
nCLK pair can accept most differential input levels.
