ICS83940D
LOW SKEW, 1-TO-18
LVPECL-TO-LVCMOS / LVTTL FANOUT BUFFER
GENERAL DESCRIPTION
The ICS83940D is a low skew, 1-to-18 LVPECL-
to-LVCMOS/LVTTL Fanout Buffer and a member
of the HiPerClockSfamily of High Performance
Clock Solutions from ICS. The ICS83940D 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/LVTTL outputs are designed to
drive 50
series or parallel terminated transmission lines.
The ICS83940D is characterized at full 3.3V and 2.5V or mixed
3.3V core, 2.5V output operating supply modes. Guaranteed
output and par t-to-par t skew characteristics make the
ICS83940D ideal for those clock distribution applications
demanding well defined performance and repeatability.
