Applications Information
Simplified Block Diagram of 5-Bit Counter
Asynchronous Programming
The 5-Bit programmable counter counts-down from the programmed value of the data bits to zero and issues an
output pulse at the end of each cycle. Settling time of the programmable 5-Bit counter is defined as the maximum
time required for the counter to change the division ratio N to a new value after the data bits have settled. The worst
case settling time occurs if the data bits A0 thru A4 are changing during the load cycle. Under this condition, the
data bits may potentially be erroneous when they are clocked in and in the worst case could be all 1’s, requiring 32
clock cycles until the correct data is re-loaded into the flip flops. The worst case asynchronous settling time can be
calculated as follows:
T
SETTLING MAX
= 32/f
IN
(For Asynchronous Programming)
As an example, if the input frequency is 1 GHz, the maximum settling time is 32 nS
