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…
Part Number: DP83848C I am using this Ethernet chip in my design. Are the 51 ohm series terminations required when I am using impedance controlled traces in my design? The datasheet calls for the series terminations of 51 ohms, but I have very short traces…
Part Number: DP83848C Other Parts Discussed in Thread: DP83822I Hi Team,
The customer used our DP83848 chip, but had some problems with the FLP waveform test.
The FLP waveform of DP83848 did not see any undershoot, and the customer wanted to know if such…
Part Number: DP83848C The data sheet for the DP83848VV in the 48-LQFPpackage TI refers to as its "PT package" apparently has a 49th pin in the form of an underside Power Pad. Is this true? There's ambiguity about this because the package drawing…
Part Number: DP83848C When selecting an RJ45 jack with built-in magnetics to use with DP83848 I note that there are two general classes of these devices. One class is known in the literature as "current driving outputs", the other "voltage driving outputs…
