we are going to design a board with iMX7S, we need to connect clock inputs / outputs to other devices.
While reading the CCM chapter on IMX7SRM the clock structure is quite clear to me,
it's not completely clear to me how the internal signals are connected to external pins.
Referring to signal names used in drawings at pages 496-799, there's not exact matching with pin names at
Furthermore, CCM_CLK1_P/N and CCM_CLK2 are not present at all...
Please complete / correct the following connection table:
PIN (direction) <---> SIGNAL
CCM_CLK1_P / CCM_CLK1_N (input / output) <---> ?
CCM_CLK2 (output) <---> ?
CCM_CLKO1 (output) <---> CCM_CLKO1
CCM_CLKO2 (output) <---> CCM_CLKO2
CCM_ENET1_REF_CLK (output) <---> ?
CCM_ENET2_REF_CLK (output) <---> ?
CCM_ENET3_REF_CLK (output) <---> ?
CCM_EXT_CLK1 (input) <---> CCM_EXT_CLK1
CCM_EXT_CLK2 (input) <---> CCM_EXT_CLK2
CCM_EXT_CLK3 (input) <---> CCM_EXT_CLK3
CCM_EXT_CLK4 (input) <---> CCM_EXT_CLK4
NOTE: In another post CCM_CLK2 is defined as input only... what is correct?
