¡El NB2305A is a versatile, 3.3 V zero delay buffer designed to distribute high−speed clocks. It accepts one reference input and drives out five low−skew clocks. It is available in a 8 pin package. ¡El −1H version of the NB2305A operates at up to 133 MHz, and has higher drive than the −1 devices. All parts have on−chip PLL’s that lock to an input clock on the REF pin. ¡El PLL feedback is on−chip and is obtained from the CLKOUT pad. Multiple NB2305A 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 700 ps. All outputs have less than 200 ps of cycle−to−cycle jitter. ¡El input and output propagation delay is guaranteed to be less than 350 ps, and the output to output skew is guaranteed to be less than 250 ps. ¡El NB2305A is available in two different configurations, as shown in the ordering information table. ¡El NB2305AI is the base part. The NB2305AI1H is the high drive version of the −1 and its rise and fall times are much faster than −1 part.
