Hi Patrick,
True, there are several internal power rails in the TLK100. However the xfmr CT is connected to the main supply. If you look at Fig 2-1 on page10, and Fig 2-2 on page 11, and most importantly Table 2-1 on page 12, you'll see the xfmr CT…
I have questions on the TLK100.
1) From a power on reset (POR), does the PHY require that the clock is stable as it does for the Hardware reset (using the reset PIN). See data sheet section 9.6.2 RESET TIMING.
2) For a hardware reset, can table9…
I am using the TLK100 and a RJ45 w/ built-in magnetics.
I see that the termination is 50 ohm to ground on each line of Tx, Rx.
What should the PCB trace impedance be?
50 ohm single?
100 ohm differential?
Question from a customer on the TLK100- is it possible to run the PHY “unmanaged” (i.e. not utilize the SMI interface and run in some sort of default mode?)

Other Parts Discussed in Thread: TLK110 Hello, all.
Now we are designing TLK100 on our power meter application.
Then, I would like to know about the hardware design hint on the layout.
As I could find your manual, 1469 PHYTER® Design & Layout Guide…
Other Parts Discussed in Thread: TLK110 Hello,
For an external clock source, please clarify if the TLK100 Ethernet PHY really needs a "nominal voltage of 1.8V" as stated in the datasheet (see page 36 of datasheet).
I believe it should be 3.3V nominal…
A customer is using the TLK100 and found some descrepancies in the published power numbers on Page 69 table 9.5.1, our FAE states the number as 189mW running from 3.3V at 10Mb/s, please confirm this.
Also, we need to understand what is meant by, "from…
