Part Number: DP83848C Tool/software: Hi,all
I have some questions about the VTPTD_100 in the datasheet. I wonder whether it represents the peak-to-peak value of the differential signal, or the amplitude of the single-ended signal against 0V. Can someone…
Part Number: DP83848C Tool/software: Dear Sirs ,
I am working on a layout with DP83848C and I am wondering if the PFBOUT 23 can be connected with a wire under the IC with pin 18 and 37 .
I have a bit a space constraint design and if I can rout them…
Part Number: DP83848C Tool/software: We are using your DP83848CVV/NOPB. I understand that you have not published an official life cycle statement for any of your devices. However, in order to define the life cycle of our products, We would like to know…
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…
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…
Part Number: DP83848C Other Parts Discussed in Thread: DP83848J , Are TI engineers available to review a schematic design? I am working with DP83848C (RMII mode) interfacing to a PIC32MX795F512L device. What lines should be impedance controlled, just the…
Part Number: DP83848C
1. In RMII mode, MCU connects to RX-DV, but not CRS-DV.
2, RBIAS install 4.7KΩ 1% resistance.
3. PFBOUT, PFBIN1, PFBIN2 Connect to DC3.3V power supply.
The above connection. The network can be connected in actual use. Long…
Part Number: DP83848C I'm using DP83848 with 10BASE.
I believe the length of preamble is defined 7 octets in IEEE standards. However, the DP83848 sometimes outputs preamble 6.5 octets + SFD (1octet).
Is this preamble shortage common on the ethernet…
