ICS83940
LOW SKEW, 1-TO-18
LVPECL-TO-LVCMOS/LVTTL FANOUT BUFFER
GENERAL DESCRIPTION
The ICS83940 is a low skew, 1-to-18 LVPECL-
to-LVCMOS/LVTTL Fanout Buffer and a member
of the HiPerClockS family of High Performance
Clock Solutions from ICS. The ICS83940 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 ICS83940 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
ICS83940 ideal for those clock distribution applications de-
manding well defined performance and repeatability.
