NB2304A

www.DataSheet4U.com NB2304A 3.3 V Zero Delay Clock Buffer The NB2304A is a versatile, 3.3 V zero delay buffer designed to distribute high−speed clocks in PC, workstation, datacom, telecom and other high−performance applications. It is available in an 8 pin package. The part has an on−chip PLL which locks to an input clock presented on the REF pin. The PLL feedback is required to be driven to FBK pin, and can be obtained from one of the outputs. The input−to−output propagation delay is guaranteed to be less than 250 ps, and the output−to−output skew is guaranteed to be less than 200 ps. The NB2304A has two Banks of two outputs each. Multiple NB2304A devices can accept the same input clock and distribute it. In this case, the skew between the outputs of the two devices is guaranteed to be less than 500 ps. The NB2304A is available in two different configurations (Refer to NB2304A Configurations Table). The NB2304Ax1* is the base part, where the output frequencies equal the reference if there is no counter in the feedback path. The NB2304Ax1H is the high−drive version of the −1 and the rise and fall times on this device are much faster. The NB2304Ax2 allows the user to obtain REF, 1/2 X and 2X frequencies on each output Bank. The exact configuration and output frequencies depend on which output drives the feedback pin.
