Timing parameters are obtained with 10pF loading on the EMIF pins.
E = SYSCLK period in ns. For example, when SYSCLK is set to 60 or 100 MHz, E = 16.67 or 10 ns, respectively. For more detail on the
EM_SDCLK speed see Section 5.9.2 , EMIF Non-Mobile and Mobile Synchronous DRAM Memory Supported .
When CV DD = 1.05 V, and DV DDEMIF = 3.3 V, 2.75 V or 2.5 V, the max clock frequency on the EM_SDCLK pin is limited to 60 MHz
(EM_SDCLK = 60 MHz). For more information, see TMS320C5515/14/05/04 DSP External Memory Interface (EMIF) User's Guide
(literature number SPRUGU6 ).
When DV DDEMIF = 1.8 V, the max clock frequency on the EM_SDCLK pin is limited to 50 MHz (EM_SDCLK = 50 MHz). For more
information, see TMS320C5515/14/05/04 DSP External Memory Interface (EMIF) User's Guide (literature number SPRUGU6 ).
