I’m currently investigating if the LS1012A could be used for my next design.
While reading the QorIQ LS1012A Reference Manual, I found that (as I understand it) you can’t use a crystal as the main clock, if SATA is enabled. However when I look at the LS1012A RDB reference design board, it uses a 25MHz crystal and has a SATA connector, and Thus I would assume SATA can be enabled on the board?.
What am I missing?
From LS1012A Reference Manual:
“188.8.131.52.4 SATA use cases
For the systems with a SATA interface, an external clock oscillator/generator is required,
as shown in the figure below:
Figure 4-10. SATA clocking
Crystal cannot be used when SATA is enabled on the chip."
