FemtoClock® Crystal-to-LVCMOS/LVTTL Frequency Synthesizer

840304I is an optimized PCI-X and PCI-e clock generator and a member of the family of high performance clock solutions from IDT. The 840304I uses a 25MHz parallel crystal to generate 33.33MHz to 133.33MHz clock signals, replacing solutions requiring multiple oscillator and fanout buffer solutions. The device supports 1% downspread spread spectrum clocking. The 840304I has excellent phase jitter (<1ps rms) over integration range of 1.5MHz - 22MHz. Designed for Backplane, networking and industrial applications, the 840304I can also drive the high-speed PCI-X and PCI-e SerDes clock inputs of communication processors, DSPs, switches and bridges.
