SJA1105 RMII ref_clk configuration

[bwp530]

S32K344(mac mode) connect to SJA1105(phy mode) with RMII on our board.

the PTD6_RMII_TX_CLK connet to K14_REF_CLK of SJA1105.

the datasheet of sja1105 shows that the REF_CLK can output 50Mhz for PTD6_RMII_TX_CLK .

How can I configure the chip to output 50Mhz?

Hi,

please refer to chapters 6.1.7 to 6.1.9 of the AH1704 SJA1105PQRS Application Hints, to know how REF_CLK can be configured/handled in RMII modes.

I configure the sja1105 to mac mode to get the ref_clk out, is it right?
