  • ADC3443: quenstions about ADC3443 SYSREF pin and LVDS output pins

    Part Number: ADC3443 Hi we have some quenstions about ADC3443. first one , how to connect sysref pin to the FPGA pins ,the FPGA dataoutput pins are LVDS 2.5V level.As the figure below shows the connection status. the second questions is about…

  • ADC3443: Devices synchronization problem

    TI Thinks Resolved
    Part Number: ADC3443 Hi Team, Posting on behalf of our customer. I have a question about how to achieve synchronization among multiple ADC3443 devices. There are four devices on the board. In the datasheet of ADC3443, the sysref pin can be used…

  • TSW1418EVM: Compatible with ADC3443 or ADS4242 EVMs?

    Part Number: TSW1418EVM Other Parts Discussed in Thread: ADS4242 , ADC3443 , , TSWDC155EVM Tool/software: Hello, Is the TSW1418EVM compatible with the ADC3443 or ADS4242 EVMs? If not, what is the best path forward to evaluate the ADC3443 or ADS4242…

  • ADC3443: PCN status check

    TI Thinks Resolved
    Part Number: ADC3443 I’m fairly advanced in designing in the ADC3443 and now looking at the detail on the design. I came across this PCN (on the Digikey site) https://media.digikey.com/pdf/PCNs/Texas%20Instruments/PCN20161114000.pdf Is this…

  • ADC3443: SYSREFM LVDS inputs, do they have internal 100 ohm resistors?

    TI Thinks Resolved
    Part Number: ADC3443 SYSREFM LVDS inputs needs an external termination? I’m 90% sure that it doesn’t as there is no mention of termination in the D/Sheet or in the reference design. I was just wondering if you can confirm that the 100R LVDS termination…

  • ADC3443: When I use FPGA LVDS driver pin for SYSREF , do they need Coupling capacitor?

    Resolved
    Part Number: ADC3443 Hi, We will use the FPGA's LVDS driver to drive SYSREF. The output characteristics of this driver are 1.25V common mode voltage and 0.25 ~ 0.6V differential swing. I realized in past thread that this circuit requires an external…

    Hi, ADC3443 does not have digital gain feature. Regards, Sourabh

  • ADC3443: Input Voltage

    TI Thinks Resolved
    Part Number: ADC3443 Hello I would like to know if and how I can set an input voltage different from 2Vptp ? It is written in the datasheet (page 6) for frequencies < 600 MHz: 1Vptp. Do you stay with 14 bits at 1 Vptp ? How does the GUI take into…

  • ADC3443: multi chip synchronization

    TI Thinks Resolved
    Part Number: ADC3443 Hello, I would like to know how to perform multi chip ADCs synchronization when I'm using only LVDS wires and not JESD204B, and when I'm not using the internal ADC clock divider ? Thanks for your support Lolo

  • ADC3443: Interfacing with pseudo-differential sensor output

    TI Thinks Resolved
    Part Number: ADC3443 Other Parts Discussed in Thread: THS4541 Hi, I have a pseudo-differential output from a sensor that has to be conditioned to match the input of the ADC with optimal noise performance. The signal has the following shape : …
