Overview

The ARM® Artisan® DLL (Delay Locked Loop) is the ideal solution for the 90 degree clock delay needed in many source-synchronous, double-data rate systems. The master DLL cell provides a precise 90 degree phase shifted data strobe (DQS/DQSB) to slave DLLs by continuously measuring the period of the memory controllers reference clock and creating an accurate digital code to represent the data shift. This accurate performance is enabled even at low frequencies, allowing low-speed functional testing and reliable data timing down to 10MHz. The robust Artisan DLL is electrically and physically tuned for the TSMC 65nm GP process and uses a 2.5V thick-oxide device for high voltage protection and optimum I/O and core power consumption. The Artisan DLL provides the precision, performance and voltage requirements necessary to implement reliable DDR PHY solutions.
