ICS83940I
LOW SKEW, 1-TO-18
LVPECL-TO-LVCMOS FANOUT BUFFER
GENERAL DESCRIPTION
The ICS83940I is a low skew, 1-to-18 LVPECL-
to-LVCMOS Fanout Buffer and a member of the
HiPerClockS family of High Performance Clock
Solutions from ICS. The ICS83940I has two
selectable clock inputs. The PCLK, nPCLK pair
can accept LVPECL, CML, or SSTL input levels. The
LVCMOS_CLK can accept LVCMOS or LVTTL input levels.
The low impedance LVCMOS outputs are designed to drive
50
series or parallel terminated transmission lines.
The ICS83940I is characterized at full 3.3V, full 2.5V and mixed
3.3V input and 2.5V output operating supply modes. Guaran-
teed output and part-to-part skew characteristics make the
ICS83940I ideal for those clock distribution applications de-
manding well defined performance and repeatability.
