Part Number: TMS320C6678

I'm gathering information about the maximum clock speed allowed for C6678 DSP.

Problems arise when consulting TI's official documentation:

I'm a little bit confused.

Which one is right?

I just want to be sure so, does all the C6678 support this clock speed? Are there any limitation?

All TMS320C6678 support 1400 MHz clock speed. There is no limitations but you should pay attention on the power supply voltage - CVDD voltage range will be 0.9 V to 1.1 V for 1000-MHz and 1250-MHz devices and 0.95 V to 1.15 V for 1400-MHz device. For more details refer to data sheet:
