The device is configured using a software driver. The following code is an example of calls to the driver:
28529-DSH-001-K
The Rx IDCR clock is synthesized using the RxClAv input from the PHY side UTPOIA bus. This is performed
on a per group basis; that is, one link in each group is selected (via software) to provide the Rx IDCR for that
group.
IMA_SysClk must be greater than or equal to 40.96 MHz (less than 24 ports) and be greater than or equal to
49.152 MHz if there are more than 24 ports.
Either IMA_SysClk or IMA_RefClk can be used as the Tx IDCR clock:

IMA_LINK_TYPE = IMA_VAR_RATE
IMA_DSL_REF_CLK_FREQUENCY = 40960000
IMA_DSL_USE_REF_CLK2 = IMA_INACTIVE
IMA_DSL_REF_GENERATOR = IMA_ACTIVE
IMA_ALT_RX_TRL = IMA_ACTIVE
IMA_GRP_LINK_BANDWIDTH = 2304 (grp#)
IMA_GRP_CLK_REF_FACTOR = IMA_NO_DIV (grp#)
IMA_GRP_TX_TRL_SRC = IMA_REF_XCLK (grp#)
IMA_GRP_RX_TRL_SRC = IMA_RX_TRL_(x) (grp#)
IMA_SysClk may be used if it is an 8 kHz multiple of the bit rate.
IMA_RefClk may be used if it is an 8 kHz multiple of the bit rate and greater than or equal to 4.64 MHz.
