There are four different types of resets available on a TI Ethernet PHY, each with it's own use case.
Pin Reset: Activated by asserting the Reset pin low. Digital core is reset, link up process will restart. All internal registers will reinitialize…
Other Parts Discussed in Thread: TCAN1043A-Q1 Introduction
Any CAN transceiver that has an Inhibit (INH) pin will also have a sleep mode. The purpose of the INH pin is to be able to automatically turn off the voltage regulator for your MCU/Board. This…
Part Number: DP83867E Other Parts Discussed in Thread: USB-2-MDIO To force a specific speed, auto-negotiation is left enabled while disabling advertisements for all non-desired speeds.
The scripts to do this in the USB-2-MDIO interface for the DP83867…
There are several different tools available in a Linux environment to read and write registers on a TI PHY. Several of these options are listed below.
MII read: This is the only command which can and must be used in U-boot. Stop the autoboot process…
Part Number: DP83TC812S-Q1
For DP83TC812S/R and DP83TC814-Q1 if clkout pin is not being used to provide a clock signal to another component, then it is recommended to shut down this clock output and reduce its impact on EM emissions.
Clkout's output…
TI does not have a recommendation for any specific conformal coat or underfill product.
In some temperature ranges these materials can be detrimental if the conformal coating or underfill product has a mismatched CTE vs. solder joint (Z axis). This…
Part Number: DP83867IR DP83867 PHY (and other TI industrial and automotive PHYs) have the capability to :
1. Generate the packetized data
2. Capture the number of frames received
3. Capture the number of frames received with errors.
These parameters…
