puts. The CLK, nCLK pair can accept most standard differen-
tial input levels. The PCLK, nPCLK pair can accept LVPECL,
LVDS, CML, or SSTL input levels. The clock enable is inter-
nally synchronized to eliminate runt pulses on the outputs dur-
ing asynchronous assertion/deassertion of the clock enable
pin.
Guaranteed output skew and part-to-part skew characteristics
make the ICS853031 ideal for high performance workstation and
server applications.
