This section describes the operating
conditions of the device. This section also contains the description of each
Operating Performance Point (OPP) for processor clocks and device core clocks.
Table 7-1 describes the maximum supported frequency per speed grade for the device.

(1) Max VPAC and DMPAC speeds not available concurrently due to
PLL sharing (max combinations are 720/480 and 650/520 for VPAC/DMPAC,
respectively.
(2) Maximum DDR Frequency will be limited based on the specific memory type (vendor)
used in a system and by PCB implementation. TI strongly recommends all designs
to follow the TI LPDDR4 EVM PCB layout exactly in every detail (routing,
spacing, vias/backdrill, PCB material, etc.) in order to achieve the full
specified clock frequency. Refer to the Jacinto 7 DDR Board Design and Layout
Guidelines for details.
(3) Refer to Device Comparison table to determine specific part numbers that include
1x VENCDEC module (480 MP/s) or 2x VENCDEC module (960 MP/s)
