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.

Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit
values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied,
damage may occur and reliability may be affected.

NB2308A
Zero Delay and Skew Control
All outputs should be uniformly loaded to achieve Zero
Delay between input and output.
To close the feedback loop of the NB2308A, the FBK pin
can be driven from any of the eight available output pins.
The output driving the FBK pin will be driving a total load
of 7 pF plus any additional load that it drives. The relative
loading of this output (with respect to the remaining outputs)
can adjust the input−output delay. This is shown in Figure 3.
For applications requiring zero input−output delay, all
outputs including the one providing feedback should be
equally loaded. If input−output delay adjustments are
required, use the above graph to calculate loading
differences between the feedback output and remaining
outputs. For zero output−output skew, be sure to load outputs
equally.
