DDR2 IO 2.5V ST with 800MHz PLL / 800Mbps DLL - TSMC 65 nm CLN65GP

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 controller’s 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.
The ARM® Artisan® Deskew Phase Locked Loop (PLL) is a two output, programmable, frequency synthesizer macro cell designed specifically for clock generation. The Deskew PLL ensures accurate frequency optimization and is designed to remove the skew between the output of a clock and the clock reference. This PLL-based frequency synthesizer generates robust signals from 100MHz to 800MHz using an internal loop filter and active bandwidth regulator, providing maximum noise immunity and minimum jitter. Electrically and physically tuned to the TSMC 65nm GP process, the Artisan PLL provides optimum frequency operation and power consumption for precise, dependable implementations.
