843252AGLF Overview
The ICS843252 is a 2 differential output LVPECL Synthesizer designed to generate Ethernet referHiPerClockS™ ence clock frequencies and is a member of the HiPerClocks™ family of high performance clock solutions from ICS. Using a 19.53125MHz or 25MHz, 18pF parallel resonant crystal, the following frequencies can be generated based on the settings of 4 frequency select pins (SEL[A1:A0], SEL[B1:B0]): 625MHz, 312.5MHz,...
