ICS845204 Description
The ICS845204 is a 4 output PCI Express clock ICS synthesizer optimized to generate low jitter PCI HiPerClockS™ Express™ reference clocks with or without spread spectrum modulation and is a member of the HiPerClockS™ family of high performance clock solutions from IDT. Spread type and amount can be configured via the SSC control pins. Using a 25MHz, 18pF parallel resonant crystal, the device will generate M-LVDS...
