Contextual Info: High-Speed Synchronous Prescaler Counter  XAPP 001.002 Application Note By PETER ALFKE AND BERNIE NEW Summary Borrowing the concept of Count-Enable Trickle/Count-Enable Parallel that was pioneered in the popular 74161 TTL-MSI counter, a fast non-loadable synchronous binary counter of arbitrary length can be implemented efficiently in XC3000-series LCA devices. For best partitioning into CLBs, the counter is segmented into a series of
