HiPerClockS™
selectable clock inputs. The CLK, nCLK pair can accept most
standard differential input levels. The device can operate
using a 3.3V LVPECL (V
3.3V ECL (V
ferential architecture and low propagation delay make it
ideal for use in clock distribution circuits. The select pins have
internal pulldown resistors. Leaving one input unconnected
(pulled to logic low by the internal resistor) will transform
the device into a 2:1 multiplexer. 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 CLK0, nCLK0).
The ICS85357-01 is a 4:1 or 2:1 Differential-to-
3.3V LVPECL / ECL clock multiplexer which can
operate up to 750MHz and is a member of the
HiPerClockS™ family of High Performance Clock
Solutions from ICS. The ICS85357-01 has 4
