NB2305A
3.3 V Zero Delay
Clock Buffer
The NB2305A is a versatile, 3.3 V zero delay buffer designed to
distribute high
speed clocks. It accepts one reference input and drives
out five low
skew clocks. It is available in a 8 pin package.
The
1H version of the NB2305A operates at up to 133 MHz, and
has higher drive than the
1 devices. All parts have on
chip PLL’s that
lock to an input clock on the REF pin. The PLL feedback is on
chip
and is obtained from the CLKOUT pad.
Multiple NB2305A 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 350 ps, and
the output to output skew is guaranteed to be less than 250 ps.
The NB2305A is available in two different configurations, as shown
in the ordering information table. The NB2305A1 is the base part. The
NB2305Ax1H* is the high drive version of the
1 and its rise and fall
times are much faster than
1 part.
