Hi Frederic,

TX_TCLK is available on CLKOUT pin of the device. On the EVM, CLKOUT is available on J16. You can solder an SMA connector on J16 to access the clock.

Please use the following register IO_MUX_CFG Register (Address = 0x170)
Bits [12:8] can be used to choose TX_TCLK for the channel of your requirement.

You can refer to section 9.6.1.44 of the datasheet for the bit descriptions. https://www.ti.com/lit/ds/symlink/dp83869hm.pdf

Please let me know if you need more details.

Hi Gokul,

Thanks

Before I read the Value of the register Adresse 0x170

the Register value is 0C10 configured with 0xC = Reference clock (synchronous to XI input clock

the Frequency value J16 is 25Mhz

I set in the register 0x170 -> 0810 (0x8 = Channel A transmit clock)

Expected value on j16 should be 125Mhz but I measured always 25Mhz

Hi Frederick,

Along with the above register, can you please program reg<0x00C6> = 0x0010 too?
