hI,
Good day,
Thanks for the previous support.
Previously we using the ethernet controller (DP83848J) with Rj45 ( 7498010210A) and TI controller (TMS320F28384D).
Now we changed the Ethernet controller (LAN8710A) with Rj45 ( 7498010210A) and TI controller …

Hi
Please help to suggest the schematic design. In the actual test, Network cables are properly connected in RMII mode, but cannot be connected in MII mode.
The problem with MII schema validation is as follows
1. There is no output…
Part Number: DP83848J Is there a "flowchart" of sorts for setting up this PHY using the MDIO bus? The datasheet has detailed register descriptions but no clear information about a reliable sequence of peeks and pokes that establish link setup…
Part Number: DP83848J Hi team,
We're selecting crystal for this device referencing from datasheet, SNLA079D and SNLA290.
we understand CL(load capacitance) is recommended 8pF to 20pF from SNLA290.
On the other hand, in datasheet says 25pF to 40pF…
Part Number: DP83848J Hi team,
In datasheet, RESERVED pin(8,9,10 pin) is said that had to be left unconnected.
If this pin is pulled up to VCC with 4.7kohm resistance, are there any effect to function?
Our customer design with reference to commercial…
Part Number: DP83848J hi team:
my customer use DP83848 PHY, but they has some limitation of the PCB layout ,so they want to confirm the maximum trace length from the PHY to RJ45 side .
meanwhile , the MAC to PHY is recommendation under 2 inches after checking…
Part Number: DP83848J Dear TI. I am using the ARTY A7 100T baord with your PHY on it.
The PHY's Basic Mode Status Register and PHY Status Register shows the correct link status. I can plug and unplug my cable and it shows accordingly. But I noticed…
Part Number: DP83848K Other Parts Discussed in Thread: DP83848J Hello,
I'm looking at the swapping the DP83848J with the DP83848K for the higher industrial temperature grade. Is the only difference between the two parts the temperature rating and…
Part Number: DP83848J Other Parts Discussed in Thread: DP83620
Hi Team,
Due to out of stock, customer wants to know what is closest replacement for this device, no need to be p2p, just similar function, same MAC interface, thanks for advice!

Part Number: DP83848J Dear Specialists,
My customer wrongly connected 4.87ohm resistor to the RBIAS(20pin). It should be 4.87kohm.
In this case, what kind of impact is expected.
We are concerned that the resistance of the RBIAS pin is lower than expected…
