  • DP83848C: Interface forum

    Part Number: DP83848C Tool/software: Hi, I’m working on a prototype which uses the DP83848C to interface to an ESP32 using RMII. At present I’m unable to configure the PHY start up with auto-negotiation enabled. I use pins 26 and 28 to drive…

  • DP83848C: Reference code for the end of the sequence

    TI Thinks Resolved
    Part Number: DP83848C Tool/software: Hi, May I ask if there is a reference code for the end of timing when using the DP83848 chip on the FPGA? Thanks!

  • DP83848C: Violate RMII Transmit timing requirement, is there any solution?

    TI Thinks Resolved
    Part Number: DP83848C Tool/software: Hi team, My customer is testing DP83848C on their PCB. They found a problem: the RMII transmit timing of their MAC cannot meet the requirements of DP83848. The "TXD[1:0], TX_EN, Data setup to X1 rising time" is required…

  • DP83848Q-Q1: I want to differentiate between DP83848Q and DP83848C in driver code

    TI Thinks Resolved
    Part Number: DP83848Q-Q1 Other Parts Discussed in Thread: DP83848C Tool/software: Hello support team, The datasheet of DP83848Q-Q1 states the Vendor Model is 0xA: but the register reads 0x9. The datasheet of DP83848C states the Vendor Model is 0xA too…

  • DP83848C: HLQFP and LQFP thermal pad size

    TI Thinks Resolved
    Part Number: DP83848C Tool/software: Hi Team, As title, do we have information can be referred? I learned the other thread https://e2e.ti.com/support/interface-group/interface/f/interface-forum/1160974/dp83848i-ground-pad-size-and-conncection/4365992…

  • DP83848C: RMII design

    Part Number: DP83848C I have a conflict it seems with regard to DP83848C RMII bus impedance. The datasheet references the IEEE spec of 68 ohms for the bus impedance, but the TI design review package I received states 50 ohms for RMII interface. Can I…
