ICS843004-01 Overview
The ICS843004-01 is a 4 output LVPECL synthesizer optimized to generate Ethernet HiPerClockS™ reference clock frequencies and is a member of the HiPerClocksTM family of high performance clock solutions from ICS. Using a 25MHz 18pF parallel resonant crystal, the following frequencies can be generated based on the settings of 2 frequency select pins (F_SEL[1:0]): 156.25MHz, 125MHz, 62.5MHz.
