Part Number: DP83849C Hi,
"Bias Resistor Connection: A 4.87 kΩ 1% resistor should be connected from RBIAS to GND."
Using DP83849 or DP83822, as 4.87K 1% resistor is not commonly used, is it possible to use 4.85K 1% resistor?

Dear Technical Support Team,
I'm checking the difference between I grade and C grade.
Is this typo following ?

Part Number: DP83849C Other Parts Discussed in Thread: DP83848C , DP83849I , DP83620 Hi,
We are using Linux LTS v6.1.58 on i.MX6Solo where we have SJA1105Q Switch connected to Dual-port DP83849C PHY. Switch, SJA1105Q is configured in DTS with DP83849C…
Part Number: DP83849C The customer is using an MCU that has one MAC built in, but their application requires the use of 2 Ethernet RJ45 connectors at 10/100 Mbps. Can the DP83849 dual ports both be controlled with one MAC interface?
Part Number: DP83849C Other Parts Discussed in Thread: DP83849I Hi Experts,
Due to the supply shortage issue of DP83849I, my customer is going to use DP83849C. What are the differences between these devices?

Part Number: DP83849C Hi,
Maybe you are able to reference Case CS0132290 solution as well.
The issue I have is I would like to identify connections between qty 2 RJ45 connectors and the DP83849C as well as the connections between the DP83849C and…
Part Number: DP83849C Other Parts Discussed in Thread: DP83849I , Hi,
I'd like to ask about the difference points between DP83849C and DP83849I as below,
1. Are these 2 version using same chip?
2. I think that the pin assign differences of DP83849C…
Hi Frank,
The difference is the architecture of the line driver. If the CT's are pulled to ground, and there are no termination resistors, then it is likely a voltage mode line driver.
The DP83848 has a current mode line driver, and as such, needs…

Hi TI,
Why there are two 3.3V in the TCT/RCT and pullup resistors in following picture
But there is only one 3.3V in TCT and pulldowns 49.9 ohm to ground
Best regards,

Part Number: DP83849C Dear DP83894c Experts,
I would like to run a RJ-45 loopback test; that is with a plug on the RJ45 that loops the TX data to RX.
Post reset, are there any registers that I must configure in order to see a successful loopback…
