Part Number: DP83TC811R-Q1
Hi,
Customer want to know more about the power up timing of the device.
Basically, they need to know what exactly mean by T5.5 and T5.8.
1. "Post power-up stabilization-time prior to MDC preamble for register access"…
Part Number: DP83TC811R-Q1 Hi Team,
For 811,
Does it have error packet counter for receive and transmit as CAN error frames?
I only find below in datasheet.
Part Number: DP83TC811R-Q1 Hi,
My customer report the compliance test result of Test Mode5 Transmitter Peak Differential Output is out of spec, see attached report.
The spec upper limit is 2.2VPP, but they got 3.166VPP.
Customer ever tried to modify LDG_CTRL1…
Part Number: DP83TC811R-Q1 Hi,
My customer want to test Transmitter Distortion and Return Loss under Mode 4 pattern, but got no signal feedback from scope.
May I know how do we check the settings are correct? Or any procedure?
For return loss, it looks…
Part Number: DP83TC811R-Q1 Dear team,
My customer asks me whether we can use register to power down our device. I found that our 0x00 bit[11]=1 means IEEE power down. I don't understand what is the difference between IEEE power down and our power down state…
Part Number: DP83TC811R-Q1 Hi team
I would like to ask the question related to the ethernet transmission test:
For the test of Ethernet network transmission, we can generally monitor the packet loss rate, or directly use two hosts to PING each other to…
Part Number: DP83TC811R-Q1 Dear team,
Do we support below cable diagnostics?
1. short between MDI+ and MDI-
2. MD+/MDI- short to GND
3. MD+/MDI- short to power
Thanks & Best Regards,

Part Number: DP83TC811R-Q1 Other Parts Discussed in Thread: DP83TC811S-Q1 Hi team,
Do you have set_loopback code to initial the interface? My customer need use MTK plantform MT2731, in main code it have include name code set_loopback.
thank you!
Part Number: DP83TC811R-Q1 Other Parts Discussed in Thread: DP83TC811EVM I will use DP83TC811R-Q1 to communicate my HUD board , but how do I verify that DP83TC811R-Q1 is functioning normally? Is there a test board or GUI for DP83TC811R-Q1 ?

Part Number: DP83TC811R-Q1 Dear team,
My customer use our 811 RGMII interface, and MAC is TC397. They feedbacks that TC397 needs a 125MHz reference clock, but our CLKOUT is 25MHz. Do we have any method to configure CLKOUT to output 125MHz?
Thanks & Best…
