DSP编程 The TMS320VC5506/C5507/C5509A USB peripherals can be clocked from either the USB APLL or the USB DP

The TMS320VC5506/C5507/C5509A USB peripherals can be clocked from either the USB APLL or the USB DPLL. Since the APLL is inherently more noise tolerant and has less long-term jitter than the DPLL, it is recommended that you switch to it for any USB operations.
