Frequent questions

  • [FAQ] TDP142: How do I debug the issue of a monitor having no display?

    Part Number: TDP142 I have a DP monitor that does not display, how do I debug this issue?

  • [FAQ] The datasheet for this LIN transceiver states it is compliant with LIN 2.0, 2.1, and 2.2A. Is it also compliant with LIN 1.3?

    Yes, it is. The changes from LIN 1.3 to LIN 2.0 and above are purely LIN protocol changes. The physical layer transceiver definition was not affected directly or through the protocol changes. For more information on the changes to the LIN specification…

  • [FAQ] CAN 5V and 3.3V CAN transceiver operate on the same bus together?

    Yes, they can. 3.3V CAN transceivers are designed to have their recessive level, dominant and recessive thresholds such that they will correctly transmit and receive messages from either a 5V or a 3.3V CAN transceiver. Within the 3.3V CAN transceiver…

  • [FAQ] My MCU uses 3.3V as the logic supply, do I need a 3.3V CAN transceiver?

    Unless you are working with a 3.3V CAN bus, you do not need a 3.3V CAN transceiver. There is a difference between 3.3V CAN transceivers and CAN transceivers with the ability to accept 3.3V logic levels. 3.3V CAN transceivers use a 3.3V VCC supply voltage…

  • [FAQ] Can I leave "...." pin floating on my I2C I/O expander or I2C switch? (INT, Reset, Port I/O, ect.)

    For I2C I/O expanders and switches, what happens if I leave a pin floating (such as an interrupt pin, Reset pin, I/O pin, ect.)?

  • [FAQ] SN65DSI86: Can DSI86 support 4k2k 60Hz?

    Part Number: SN65DSI86 I have a eDP panel which supports 3840 x 2160 at 60Hz 24bpp resolution. Can the DSI86 support this resolution?

  • [FAQ] DS125DF1610: How to setup the device to generate different PRBS pattern

    Part Number: DS125DF1610 Sometimes for development/test purpose, you may want to have a 10GbE PRBS generator. How would you setup DS125DF1610 to generate these different PRBS patterns.

  • [FAQ] DS125DF1610: How to setup DS125DF1610 cross point registers?

    Part Number: DS125DF1610 You have different trace lengths on inputs of the DS125DF1610 device. How do you set up cross point registers to allow every channel CTLE to adapt to it's incoming signal loss characteristics?

  • [FAQ] DS125DF111: How to determine the data rate that device is lock to?

    Part Number: DS125DF111 DS125DF111 is locked and you want to know what is the data rate that device is locked at. What are the settings to determine DS125DF111 locked rate?

  • [FAQ] LMH0303: How to setup LMH0303EVM to operate in Pin mode or use external SMBus controller?

    Part Number: LMH0303 Other Parts Discussed in Thread: LMH0318 , SIGCONARCHITECT , LMH0397 , , LMH0307 , USB2ANY LMH0303EVM/LMH0307EVM GUI was developed using win XP OS. Majority of PCs now run win10 and it is incompatible with LMH0303EVM GUI. How do we…
