Other Parts Discussed in Thread: DP83848C
There is a conflicting information between TI's design guide and TI's datasheet. Which is right, which is typo?
Has TXD_3 internal PD resistor or not?
Datasheet says at chapter 7, there is PD on TXD_3.
DP83848x PHYTER Mini / LS Single Port 10/100 MB/s Ethernet Transceiver datasheet (Rev. E) (ti.com)
Design guide says at at chapter 3 Pin and Signal Definitions, TXD[3:2] should be pulled low to put these inputs in a known state.
DP83848 Sin 10/100Mb/s Ethernet Transcvr Reduced Media Indep Interfce RMII Mode (Rev. A) (ti.com)
As I know, DP83848K documentation was made from DP83848C, where TXD_3 was STRAP input for SNI_MODE, with PD. But this modul is gone away from silicon at type J/K and maybe this is typo in datasheet.
+1:
As I know TXD_2 has not internal PD. So, this is a floated input. Please confirm it.
Thank you in advance.
