GENERAL DESCRIPTION

The ICS853058 is an 8:1 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 ICS853058 has 8 differential selectable clock inputs. The PCLK, nPCLK input 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 SEL2 pin is the most significant bit and the binary number applied to the select pins will select the same numbered data input (i.e., 000 selects PCLK0, nPCLK0).

FEATURES
