Part Number: DP83848JDP83848J data sheet reference to IEEE 68 ohm bus impedance. (section7.2.2.1)
1) Is this spec the differential impedance? Why not 50 ohms?
2) Does this spec apply if RMII is implemented?
3) Is this the impedance I need to…
Part Number: DP83848J Hi,
For the DP8384J needs to check TX/RX the rise and fall time or setup and hold time only?
seems only "PMD output Pair" needs to checked(T2.8.1)
Part Number: DP83848J Tool/software: I want to use the IBIS model to use it in CST StudioSuite, an electromagnetic simulation software, but I don't know how to connect it. How should I connect the pins of the IBIS model and with what signals?
Part Number: DP83848J Hi,
I am using an DP83848JSQ PHY connected with Switch KSZ8895MQ.
I can be able to ping the PHY IC from windows machine directly.
If I am using the Switch KSZ8895MQ in between the PHY IC and Windows PC, I can't be able to…
Part Number: DP83848J Other Parts Discussed in Thread: TPS23755 , TPS23758 Tool/software: Hello all, Recently we have had an unexpected communication issue between the Phy and ethernet. We noticed that by replacing the part we can fix it. The schematic…
Part Number: DP83848J I am using the DP83848J in conjunction with STM32F407VGT6.
The 10 MB/s works and I can read data from the controller. If I want to use the 100 MB/s, this does not work. The LED on the RJ45 socket shows me that 100 MB/s has been…
Part Number: DP83848J Hi Sir,
My cusotmer use DP83848J on their video conversion product. They have 1/10 failure rate on their MP products with differet questions:
1. Abnormal AN1 signal: they test their boards but sometimes AN1 signal show 10Mbps…
