ESCRIPTION
The ICS853054 is an 4:1 Differential-to-3.3V or
2.5V LVPECL/ECL Clock Multiplexer which
can operate up to 2.5GHz and is a member of
the HiPerClockS family of High Performance
Clock Solutions from ICS. The ICS853054 has 4
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).
