selectable differential clock inputs. The PCLKx, nPCLKx in-
put pairs can accept LVPECL, LVDS, CML or SSTL levels.
The fully differential architecture and low propagation
delay make it ideal for use in clock distribution circuits. The
select pins have internal pulldown resistors. The SEL1 pin is
the most significant bit and the binary number applied to the
select pins will select the same numbered data input (i.e., 00
selects PCLK0, nPCLK0).
The Preliminary Information presented herein represents a product in prototyping or pre-production. The noted characteristics are based on initial
product characterization. Integrated Circuit Systems, Incorporated (ICS) reserves the right to change any circuitry or specifications without notice.
