Description

The 841484I is an optimized PCIe and sRIO clock generator. The device uses a 25MHz parallel resonant crystal to generate 100MHz, 125MHz, 200MHz and 400MHz clock signals, replacing solutions requiring multiple oscillator and fanout buffer solutions. The device has excellent phase jitter suitable to clock components requiring precise and low jitter PCIe, sRIO or both clock signals. The device also supports a configurable spread-spectrum generation for PCIe applications. Designed for telecom, networking and industrial applications, the 841484I can also drive the high-speed sRIO and PCIe SerDes clock inputs of communications processors, DSPs, switches and bridges.
