Zero Delay PLL Clock Buffer Single 8-Pin SOIC N T/R

The NB2304A is a versatile, 3.3 V zero delay buffer designed to distribute high-speed clocks. It accepts one reference input and drives out four low-skew clocks. It is available in a 8 pin package. The -1H version of the NB2304A operates at up to 133 MHz, and has higher drive than the -1 devices. All parts have on-chip PLLs that lock to an input clock on the REF pin. The PLL feedback is on-chip and is obtained from the CLKOUT pad. 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 700 ps. All outputs have less than 200 ps of cycle-to-cycle jitter. The input and 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 is available in two different configurations. The NB2304AI is the base part. The NB2304AI1H is the high drive version of the -1 and its rise and fall times are much faster than -1 part.
