Part Number: TLK105
Hi,
I have been facing a strange problems. From time to time after power-up TLK105 used in my client's products is behaving like a dead one. There are no clocks generated on TX_CLK and RX_CLK lines what causes MAC layer of uC (STM32F427) not to start correctly. Hardware reset of PHY chip doesn't solve the problem and a power cycle of the the whole board is neccessary to make PHY working correctly (clocks generation), thus let the MAC layer to startup. We have checked that and only turning the PHY off and on again is able to make it work.
Is the problem known and if not, is there anything I can do to make your investigation easier?
