The issue with the clock output from the SMA port marked as RXC_TX_TCLK on the TJA1103EVB evaluation

[shilinli]

Due to the inability to access the data sheet of the automotive PHY chip corresponding to TJA1103EVB, there are currently some issues in the purchasing process. From the available EVB user manuals, there is no description of the output of the SMA port marked as RXC_TX_TCLK. Therefore, I would like to ask if the output clock is 25 MHz or 66.66 MHz? I referred to another TJA1101BHN/0Z chip, and the description of the 17th pin TXCLK in the data sheet is "transmit clock output in test mode and during slave jitter test", so I am guessing whether the SMA output marked as RXC_TX_TCLK on TJA1103EVB is 25 MHz or 66.66 MHz? If it can be determined, I will be able to make a decision on purchasing.

Hello @shilinli ,

on pin 26 - RXC/GPIO8/TX_CLK - there is 25MHz in RGMII mode and in MII mode.
