The 844S0258-07 is an eight output synthesizer optimized to generate Gigabit and 10 Gigabit Ethernet clocks. Using a 25MHz, 18pF parallel resonant crystal, the device will generate 125MHz clocks with mixed LVDS and LVCMOS/ LVTTL output levels. 844S0258-07 uses IDT's 3rd generation low phase noise VCO technology and can achieve <1ps typical RMS phase jitter, easily meeting Ethernet jitter requirements. 844S0258-07 is packaged in a small, 32-pin VFQFN package that is optimum for applications with space limitations.
