The ICS83940D is a low skew, 1-to-18 LVPECL-to-
LVCMOS/LVTTL Fanout Buffer. 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
50Ω series or parallel terminated transmission lines.
The ICS83940D is characterized at full 3.3V and 2.5V or
mixed3.3V core, 2.5V output operating supply modes.
Guaranteed output and part-to-part skew characteristics make
the ICS83940D ideal for those clock distribution applications
demanding well defined performance and repeatability.
