Integrated Device Technology, Inc. (IDT) 1. FemtoClock® Crystal/LVCMOS-to-LVDS/LVCMOS Frequency Synthesizer 8440259-45 Obsolete FemtoClock® Crystal/LVCMOS-to-LVDS/LVCMOS Frequency Synthesizer NOTICE - The following device(s) are recommended alternatives: 8440259D-45 - FemtoClock® Crystal/LVCMOS-to-LVDS/LVCMOS Frequency Synthesizer Pin-to-pin compatible The 8440259-45 is a 9 output synthesizer optimized to generate Gigabit and 10 Gigabit Ethernet clocks and is a member of the 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 8440259-45 uses IDT's 3rd generation low phase noise VCO technology and can achieve
