Description

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 selectable clock inputs. The CLK, nCLK pair can accept most standard differential input levels. The device can operate using a 3.3V LVPECL (V_EE = 0V, V_CC= 3.135V to 3.465V) or 3.3V ECL (V_CC = 0V, V_EE = -3.135V to -3.465V). The fully dif-
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 ICS85357-01 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).
