Part Number: TLK110
I designed C6748 ank TLK110 combination for ethernet interface. And I used MII mode.
After I power-on，load the program, the 3 led lights of RJ45 can be lit, while the led—act light is slightly lit, but in fact it should blink
and the chip cannot auto negotiation and link successfully, but the registers of the TLK110 can be read：
BMCR:3100 BMSR:7849 PHYSTS:0000 PHYCR:8021
then I Checked the chip level and found that the pin18, 23, 37 level is only 1.5V. I think this is the problem.
I have connected them and also connected with the correct capacitors according to the data sheet.
So what should I do with that
