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 a SMT32F407…

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,
Frank
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 of an…
Part Number: DP83849C Dear DP83849C experts,
Although the recommended VCC is 3.3 V, does anyone have any experience running the phy at 1.8 V ? Is it sufficient for development and testing ?
Kind regards,
Rocco
Part Number: DP83849C Dear DP83849c experts,
Post reset, and after having then enabling the MII loopback field, are there any other registers that must be set to assure MII loopback mode ?
Kind regards,
Rocco
Part Number: DP83849C Dear DP83849C experts,
I am using the DP83849C phy. I understand that there are 3 types of loopback tests available with this phy. They are:
- Internal BIST test. A pseudo random pattern is generated in the phy and looped from the…

I am using the DP83849C phy. After reset the speed selection bit (bit 13 of the BMCR register) is set to 1, indicating a speed selection of 100 Mbits/s.
Auto…
Part Number: DP83849C Dear DP83849C experts,
I am working with a solution that uses a DP83849C phy. I have configured the phy, and have a BIST test in internal loopback mode, and the BIST test passes.
I have made an ethernet loopback plug, and have re…
Part Number: DP83849C Dear DP83894C experts,
The spec says the following about the MII RX_ER
"MII RECEIVE ERROR: Asserted high synchronously to RX_CLK to indicate that an invalid symbol has been detected within a received packet in 100 Mb/s mode.…

Hi TI,
I'm using DP83849C,the circuit on the datasheet,the TCT and RCT pins are pulled up to 3.3V,BUT in some other network transformer circuit,the TCT and RCT pins are pulled down to ground by capacitor.
I want to know the real…
