GENERAL DESCRIPTION
The ICS844004I is a 4 output LVDS Synthesizer optimized to generate Fibre Channel reference Hi Per Clock S™ clock frequencies and is a member of the Hi Per Clocks TM family of high performance clock solutions from ICS. Using a 26.5625MHz 18p F parallel resonant crystal, the following frequencies can be generated based on the 2 frequency select pins (F_SEL[1:0]): 212.5MHz, 187.5MHz, 159.375MHz, 156.25MHz, 106.25MHz and 53.125MHz. The ICS844004I uses ICS’ 3rd generation low phase noise VCO technology and can achieve <1ps typical rms phase jitter, easily meeting...
