    Part Number: DS90UB935-Q1 Does the DS90UB935-Q1 FPD-Link interface run at 3Gbps or 4Gbps?

  • [FAQ] DS90UB954-Q1: CSI-2 Lanes SER vs. DES

    Part Number: DS90UB954-Q1 Does the number of CSI-2 lanes programmed for 954 need to match the number of input lanes for 953/935?

  • [FAQ] DS90UB953-Q1: Imager Data Rate Support

    Part Number: DS90UB953-Q1 ​​​Can the DS90UB953-Q1 support my imager?

  • [FAQ] DP83867E: How to force 10/100/1000 Mbps speed in Ethernet PHYs?

    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…

  • [FAQ] How to read and write Ethernet PHY registers using a Linux terminal?

    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…

  • [FAQ] DP83TC812S-Q1: How to disable 25MHz clock on clkout pin?

    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…

  • [FAQ] Which conformal coating is recommended for Ethernet PHY products?

    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…

  • [FAQ] DP83867IR: How to test the link-quality using DP83867's BIST and status registers?

    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…

  • [FAQ] DP83TD510E: How to check throughput without depending upon MAC?

    Part Number: DP83TD510E DP83TD510E 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…
