TMS320C6457 DSP Software-Programmable Phase-Locked Loop (PLL) Controller UG

This document describes the operation of the software-programmable phase-locked loop (PLL) controller in the TMS320C6457 digital signal processors (DSPs). The PLL controller offers flexibility and convenience by way of software-configurable multipliers and dividers to modify the input signal internally. The resulting clock outputs are passed to the C6457 DSP core, peripherals, and other modules inside the C6457 DSP.
