Part Number: DP83822I Hi,
I am using DP83822IRHBR for my design which has both RJ45 and SFP communication. Does DP83822IRHBR support Fiber optic communication?
In the datasheet it is showing IEEE 802.3u compliant: 100BASE-FX, 100BASE- TX and 10BASE-T…
Part Number: DP83822I Other Parts Discussed in Thread: TPS23731 Hi Team, I have an Ethernet and PoE design using DP83822I and TPS23731, PoE can work with TP-Link Switch(TL-SG1005P), Ethernet cable uses 2 pairs of 1236 wire but the PHY IC seems not to work…
Part Number: DP83822I Other Parts Discussed in Thread: DP83867IR , DP83825 Hi,
*1. Transformer (XFMR) specification
DP83867IR only recommends Open circuit Inductance is 320 to 350uH on XFMR specification, but we have never seen this spec on DP83822I/26I…
Hi Chand,
The new schematic looks good, except for the Chassis to Digital ground isolation. Could we change R2103 to 1MΩ? We want to create a high resistance path to separate the grounds, not a short to join them. Regarding the JXD0-0015NL, it is…
Part Number: DP83822I hi,
My customer plans to use DP83822I to support fiber network application. there are some questions as below.
1. Why 49.9 ohm pull-up resistors are added for RD_M, RD_P, TD_P and TD_N pins? what functions for these resistors…
Part Number: DP83822I Hello TI Team! I have some problems with DP83822IRHB, it couldn't work.
Section 2.4.2 (DP83822 Troubleshooting Guide) Probe the RBIAS pin says that: "Measure the DC value of the voltage across the RBIAS resistor and confirm that…
Part Number: DP83822I Hi,
We replaced PHY (was microchip) to DP83822HFRHBR.
The idea was drop-in replacement keep RGMII/MDIO exactly as in reference design.
It worked out of the box, but later we found a stange thing, 7% frame loss (tested with ping …
Part Number: DP83822I When IBIS model is performed by SIwave Ansys, we found there is a glitch waveform during turned off.
Here is wiring on the IBIS model with 50 Ohm.
Part Number: DP83822I Hi, David
I'm really sorry for late answer to the related thread.
Regarding your advice in previous thread below,
>Register 0x421 is showing that VDDIO was detected as 2.5V. We can force the detection to 3.3V using register…
