Part Number: DP83TC812S-Q1 Tool/software:
I would like to clarify the datasheet for this device.
For this PHY do AC coupling capacitors built in or need to be external? It's a little ambiguous in the datasheet.
Thank you.
Part Number: DP83TC812S-Q1 Tool/software: Dear TI supporter, My HW setting is as following The Master and slave use setting in www.ti.com/.../snla389f.pdf When set <reg><0x18C> = 0x02, the T1 bus is down, but get the status from <reg><0x18> is 0x8004…
Part Number: DP83TC812S-Q1 Tool/software: Hello,
Could you help me understand better the difference in running this PHY in master vs slave mode in SGMII mode. The configuration tool shows the difference in strapping (see below) but I wasn't able to…
Part Number: DP83TC812S-Q1 We currently have a project bringing up the PHY of an 812 chip and want to manually switch from standby to normal mode. We've tried setting 0x1C4B to register 0x18b, but this isn't working. Could you please provide a solution…
Part Number: DP83TC812S-Q1 Tool/software: Dears,
The customer has a TBOX and a gateway connected through a T1 Ethernet interface, where the MPU module on the TBOX is EC20CEFAG and the PHY is DP83TC812S, serving as the main device; The Switch of the…
Part Number: DP83TC812S-Q1 We are attempting to disable the TC10 Sleep/Wake-Up/Energy Detect functionality in the DP83TC812 PHY. However, the datasheet does not provide clear guidance on which registers need to be configured. We are aware that register…
Part Number: DP83TC812S-Q1 Tool/software: The MAC of MCU supports multiple standards:
1, SGMII without auto-negotiation: 0.1, 1 and 2.5G baud data rates with corresponding serial line rates of 0.125, 1.25 and 3.125 Gbit/s respectively 2, SGMII without…
Part Number: DP83TC812S-Q1 Hi Teams,
The customer used DP83TC812SRHARQ1 and experienced abnormal RX data output.
The 28PIN (J3_SGMII_TXCK) frequency of the PHY chip is 31MHz (stable output of 25MHz for good products), and there is no level change…
Part Number: DP83TC812S-Q1 Tool/software: Dear TI friends
I submitted a case a month ago, TI specialist told me that t he PHY cannot withstand 16V directly from the battery even if it is shorted at the connector.

Part Number: DP83TC812S-Q1 Tool/software: Hello,
I am using the ethernet phy DP83TC812 in sgmii mode.
I know that SGMII autonegociation can be disabled since its only support a fixed speed and full duplex.
However, I would like to understand more…
