Hi Jing,
Jing Liang said: Thanks, for most questions are clear for me, and if cfg_rgmii_tx_clk_shift_sel=1? then there is 2ns delay, and then if dll_tx_delay_ctrl_rgmii_sl=2.5ns, what is total delay ? 2+2.5ns?
No, it is more like one or the other. You can…
Part Number: DP83TC812R-Q1 Tool/software: Hello,
I use DP83TC812R chip on my custom board. I use QNX OS on my custom board. I try change register value of DP83TC812 on BSP and I expecting change the value of register on boot(when ethernet phy starting…
Part Number: DP83TC812R-Q1 Other Parts Discussed in Thread: DP83TC811 Tool/software: HI TI Teams
When the Ethernet PHY was changed from DP83TC811 to DP83TC812, the output low-pass filter design was removed as recommended. However, due to poorer emissions…
Part Number: DP83TC812R-Q1 Tool/software: question:The reading of PHY id is 0xFFFFFFFF, and the values of VDD are ok. May I ask what other hardware circuits may cause that the phy id cannot be read ? Or other reasons？
The hardware schematic diagram is…
Part Number: DP83TC812R-Q1 Tool/software: Hello expert，
I plan to use DP83TC812R-Q1 and dp83tg720r with PIn2PIn replacement to support 100BaseT1 and 1000BaseT1 as below blog diagram show. Is that possible to use RMII for DP83TC812R while RGMII for dp83t…

Hi
I am planning to establish a MII interface between Hercules TMS570LC43x HDK and DP83TC812x-Q1 PHY chip, but cant get any EMV that…
Part Number: DP83TC812R-Q1 Tool/software: Hello experts,
What is the power supply for DP83TC812R-Q1? (1) Rise Condition
I think several power supplies are input to the Ethernet PHY.
Is it correct that they need to be turned on at the same time?
(2)…
Part Number: DP83TC812R-Q1 Tool/software: Hi expert,
My customer need 125 MHz reference clock for RGMII. They said that industrial PHY usually has a pin to output 125MHz clock, because PHY will generate one internally.
Why automotive PHY don't have similar…
Part Number: DP83TC812R-Q1 Tool/software: Hello, we use the TIDA020047 development board and need to use the 83TC812 chip for network data transmission. However, after we configure the registers of the chip, we cannot get the output RGMII interface data…
Part Number: DP83TC812R-Q1 Other Parts Discussed in Thread: TPD1E10B06-Q1 , AM2732 Tool/software: 你好，我们使用TIDA020047开发板，需要使用83TC812芯片进行网络数据传输，但是我们配置了该芯片的寄存器后，却无法得到其输出的RGMII接口数据，通过示波器看了没有波形，不知道是否寄存器配置不正确，请帮我们核对一下：
