Manufacturer:TI Description:Figure 1 shows the connections for simple ripple carry, in which the clock period must be longer than the CP to TC de- lay of the first stage, plus the cumulative CET to TC delays of the intermediate stages, plus the CET to CP setup time of the last stage. This total delay plus setup time sets the upper limit on clock frequency. For faster clock rates, the carry loo- kahead connections shown in Figure 2 are recommended. In this scheme the ripple delay through the intermediate stages commences with the same clock that causes the first stage to tick over from max to min in the Up mode, or min to max in the Down mode, to start its final cycle. Since this final cycle requires 16 clocks to complete, there is plenty of time for the ripple to progress through the intermediate stages. The critical timing that limits the clock period is the CP to TC delay of the first stage plus the CEP to CP setup time of the last stage. The TC output is subject to decoding spikes due to internal race conditions and is therefore not recom- mended for use as a clock or asynchronous reset for flip-flops, registers or counters. Logic Equations: Count Enable = CEP • CET • PE TC = Q0 • Q1 • Q2 • Q3 • CET |
