The 8440259D-45 is a 9 output synthesizer optimized to generate Gigabit and 10 Gigabit Ethernet clocks and is a member of the HiPerClockS™ family of high performance clock solutions from IDT. Using a 25MHz, 18pF parallel resonant crystal, the device will generate both 156.25MHz, 125MHz and 3.90625MHz clocks with mixed LVDS and LVCMOS/LVTTL output levels. The 8440259D-45 uses IDT's 3rd generation low phase noise VCO technology and can achieve <1ps typical rms phase jitter, easily meeting Ethernet jitter requirements. The 8440259D-45 is packaged in a small, 5mm x 5mm VFQFN package that is optimum for applications with space limitations.
