ICS83940-01
LOW SKEW, 1-TO-18
LVPECL-TO-LVCMOS / LVTTL FANOUT BUFFER
GENERAL DESCRIPTION
The ICS83940-01 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 ICS83940-01 has
two selectable clock inputs. The PCLK, nPCLK
pair can accept LVPECL, CML or SSTL input levels. The single
ended clock input accepts LVCMOS or LVTTL input levels.
The low impedance LVCMOS/LVTTL outputs are designed
to drive 50
Ω series or parallel terminated transmission lines.
The effective fanout can be increased from 18 to 36 by
utilizing the ability of the outputs to drive two series termi-
nated lines.
The ICS83940-01 is characterized at full 3.3V, full 2.5V
and mixed 3.3V input and 2.5V output operating supply
modes. Guaranteed output and part-to-part skew charac-
teristics make the ICS83940-01 ideal for those clock distri-
bution applications demanding well defined performance
and repeatability.
