External reference crystal frequency for the PLL
PLL output frequency
PLL stabilization time
PLL stabilization time
1. An externally supplied reference clock should be as free as possible from any phase jitter for the PLL to work
correctly. The PLL is optimized for 8MHz input crystal.
2. ZCLK may not exceed 80MHz. For additional information on ZCLK and f
User Manual. ZCLK = f
3. Will not exceed 60MHz for the DSP56F801FA60 device.
4. This is the minimum time required after the PLL setup is changed to ensure reliable operation.
