AM3352: MMC_CLK MAX frequency on OPP100 of AM3352-300MHz

Motoyasu Hattori

Part Number: AM3352

Hi,

You can find "MMC_CLK = 96MHz on OPP100" on TRM P.1226. however TRM P.4218 said MMC_CLK = 48MHz. How max frequency can AM3352 support?

Please advise us.

Thanks and best regards,
M.HATTORI.

Hi Hattori,

TRM P.4218 is NOT correct. The internal MMC_CLK (CLKADPI Functional clock) max frequency at OPP100 is 96MHz.

We have MMC_CLK 48MHz max value at OPP100 only for external pin signal, in example mmc0_clk G19 pin (ZCE package).

Refer to below e2e thread for more details:

Regards,
Pavel
