The NB2308A is a versatile, 3.3 V zero delay buffer designed to distribute high−speed clocks. It is available in a 16 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.
