Part Number: DP83848-EP Tool/software: DP83848MPTBREP: For this DP83848-EP PHYTER Military Temperature Single Port 10/100, When TX_EN in MII mode is low then what is the state of TXD[0;3].
Is it in the high impedance state or low impedance state how can…
Part Number: DP83848-EP Tool/software: Here DP83848-EP PHYTER is Powered ON and in MII mode TX_EN is pulled to low what the state of pins TXD[0;3]? (Is it HiZ or what?) needed information from data sheet.
My doubt is when TX_EN is pulled low what the pin…
Part Number: DP83848-EP Tool/software: Hello Sir,
As per IEEE 802.3 Standard, Differential Output Voltage lies between 0.95V to 1.05.
we followed the test standards like :
Texas fixture board : TF-GBE-BTP 1000/100/10 BaseT Basic Test Package (consists…
Part Number: DP83848-EP Hi,
TI DP83848MPTBEP product datasheet shows that his component has Pins with Ni Pd Au Ag finish, which is new. Could this finish lead to Ag whiskers and therefore need solder dips to be added ?
Has TI mitigation on whiskers with…
Part Number: DP83848-EP Hi,
I am planning on using a DP83848-EP for my project and I would like to have a few more details on the BIST functionality of this PHY. So far I understood that to run the BIST, the following steps should be followed, thanks to…
Part Number: DP83848-EP Hi there,
We have a strange effect happening when we attempt to use the DP83848-EP chip. We are running the chip in RMII mode with Pin39 tied high and Pin6 floating (internally pulled low).
We are finding when powering on and the…
Part Number: DP83848-EP Hello,
I am using the DP83848-EP in 100BASE-TX and I am looking for the receiver specification. I have an application with several cable configurations with different length and intermediate connector numbers between the two devices…
Part Number: DP83848-EP Hello,
I am using PIC32 processor to DP83848-EP in RMII mode. I'm unable to communicate thru MDIO. Oscilloscope shows that PIC32 send out the read command, but PHY doesn't respond. Default Phy Address is 0x1. All power pins…
Part Number: DP83848I Other Parts Discussed in Thread: DP83848VYB , DP83848-EP Team, We are trying to understand if in an existing PCB design made originally for DP83848I LQFP (PT-48) the IC can be replaced by DP83848VYB HLQFP (PTB-48) / DP83848-EP HLQFP…
