NB2308A

3.3 V Zero Delay

Clock Buffer

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−outputskew is guaranteed to be less than 200 ps.

The NB2308A has two banks of four outputs each, which can be

controlled by the select inputs as shown in the Select Input Decoding

Table. If all the output clocks are not required, Bank B can be

three−stated. The select input also allows the input clock to be directly

applied to the outputs for chip and system testing purposes.

Multiple NB2308A 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.

The NB2308A is available in five different configurations (Refer to

NB2308A Configurations Table). The NB2308Ax1* is the base part,

where the output frequencies equal the reference if there is no counter

in the feedback path. The NB2308Ax1H is the high−drive version of

the −1 and the rise and fall times on this device are much faster.

The NB2308Ax2 allows the user to obtain 2X and 1X frequencies

on each output bank. The exact configuration and output frequencies

depends on which output drives the feedback pin. The NB2308Ax3

allows the user to obtain 4X and 2X frequencies on the outputs.

The NB2308Ax4 enables the user to obtain 2X clocks on all outputs.

Thus, the part is extremely versatile, and can be used in a variety of

applications.
