AD9576BCPZ

AD9576 is a dual PLL, asynchronous clock generator. It provides a multiple output clock generator function comprising two dedicated phase-locked loop (PLL) cores with flexible frequency translation capability, optimized to serve as a robust source of asynchronous clocks for an entire system, providing extended operating life within frequency tolerance through monitoring of and automatic switchover between redundant crystal (XTAL) inputs with minimized switching, induced transients. The fractional-N PLL design is based on the Analog Devices, Inc., proven portfolio of high performance, low jitter frequency synthesizers to maximize network performance, whereas the integer-N PLL provides general-purpose clocks for use as CPU and field-programmable gate array (FPGA) reference clocks. It is used in applications such as ethernet line cards, switches, and routers, baseband units, SATA and PCI express, low jitter, low phase noise clock generation, asynchronous clock generation.
