Figure 7 shows a typical block diagram of a 32‐bit divider
chain. Once again to maximize the frequency of operation
EP01 OR gates were used. For lower frequency applications
a slower OR gate could replace the EP01. Note that for a
16‐bit divider the OR function feeding the PE (program
enable) input CANNOT be replaced by a wire OR tie as the
TC output of the least significant EP016A must also feed the
CE input of the most significant EP016A. If the two TC
outputs were OR tied the cascaded count operation would
not operate properly. Because in the cascaded form the PE
feedback is external and requires external gating, the
maximum frequency of operation will be significantly less
than the same operation in a single device.
Maximizing EP016A Count Frequency
The EP016A device produces 9 fast transitioning single
ended outputs, thus VCC noise can become significant in
situations where all of the outputs switch simultaneously in
the same direction. This VCC noise can negatively impact
the maximum frequency of operation of the device. Since
the device does not need to have the Q outputs terminated to
count properly, it is recommended that if the outputs are not
going to be used in the rest of the system they should be left
unterminated. In addition, if only a subset of the Q outputs
are used in the system only those outputs should be
terminated. Not terminating the unused outputs will not only
cut down the VCC noise generated but will also save in total
system power dissipation. Following these guidelines will
allow designers to either be more aggressive in their designs
or provide them with an extra margin to the published data
book specifications.
