The ICS844008I-15 is an 8 output LVDS Synthesizer optimized to generate PCI Express HiPerClockSTM reference clock frequencies and is a member of the HiPerClocksTM family of high performance clock solutions from ICS. Using a 25MHz parallel resonant crystal, the following frequencies can be generated based on F_SEL pin: 100MHz or 125MHz. The ICS844008I-15 uses ICS' 3rd generation low phase noise VCO technology and can achieve <1ps typical rms phase jitter, easily meeting PCI Express jitter requirements. The ICS844008I-15 is packaged in a 32-pin LQFP package.
