If polarity of any of the signals is inverted, then the timing references of that signal are also inverted. (2) P = 1/SYSCLK5 clock frequency in ns. For example, when running parts at DSP frequency of 594 MHz, use P = 10.1 ns; when running parts at DSP frequency of 810 MHz, use P = 7.4 ns. (3) Use whichever value is greater. (4) The ASP does not require a duty cycle specification, just ensure the minimum pulse duration specification is met. 202 Peripheral and Electrical Specifications Copyright © 2005–2010, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Link(s): TMS320DM6446 |
