GENERAL DESCRIPTION

The AD9572 provides a multioutput clock generator function along with two on-chip PLL cores, optimized for fiber channel line card applications that include an Ethernet interface. The integer-N PLL design is based on the Analog Devices, Inc., proven portfolio of high performance, low jitter frequency synthesizers to maximize network performance. Other applications with demanding phase noise and jitter requirements also benefit from this part.
