What symbol "tsys" in SAI Electrical characteristics ?

Hello.

What undefined symbol "tsys" mean?

https://www.nxp.com/docs/en/data-sheet/IMXRT1020CEC.pdf

(In section "4.6.1 SAI/I2S switching specifications")

"tsys" mean "1 / SAIx_CLK_ROOT"?

https://www.nxp.com/docs/en/reference-manual/IMXRT1020RM.pdf

(Table 18-4. System Clock Frequency Values)

Hello Masataka Suto,

I confirmed with our experts that the SAI MCLK max frequency is 66MHz and that the BCLK max frequency is 25MHz. The tsys data in an error on the documentation and there is not such clock in the SAI module. This error will be fixed on future releases of the documentation.

We'll fix it in next document release. Thanks for pointing this error out, my apologies for the inconvenience.
