(2) For more details on the PLL, see the TMS320DM646x DMSoC Universal Serial Bus (USB) Controller User's Guide (Literature Number
SPRUER7).
(3) C = DEV_CLKIN cycle time in ns. For example, when AUX_MXI/AUX_CLKIN frequency is 24 MHz, use C = 41.6 ns and when
AUX_MXI/AUX_CLKIN frequency is 48 MHz, use C = 20.83 ns.
(4) If the USB is used, a 24-MHz, 50-ppm crystal is recommended.
