NB2304A

3.3V 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.

The NB2304Ax5H is a high−drive version with REF/2 on both

Banks.
