Frequent questions

  • [FAQ] AFE5816: AFE58xx and ADS52xx: Details about LVDS bit and Frame clock of ADS52xx and AFE58xx devices.

    Part Number: AFE5816 The LVDS bit clock and the frame clock scales down based on the decimation factor. The LVDS bit clock frequency (LCLK) is dependent on the sample rate and the type of wire interface (1-wire or 2-wire). And the sample rate is factor…

  • [FAQ] AFE58JD16: True digital TGC devices (e.g. AFE58JD16) with accurate timing of when channel gains are changed vs SPI-controlled TGC devices.

    Part Number: AFE58JD16 Digital control of TGC via SPI intended for fixed attenuation/testing. Analog control TGC is piecewise linear but it is possible to specify the timing of uniform and non-uniform time gain control using programmed settings on our…

    Part Number: AFE5801 The AFE5801 EVM ships with the adapter card for the TSW1400EVM . It does not need to be ordered separately. https://e2e.ti.com/support/applications/medical/f/30/t/503459 https://e2e.ti.com/support/applications/medical/f/30/t/…

  • [FAQ] AFE58JD18: AFE58JDxx: What should we do with unused JESD CML outputs pin, CLK_1X, CLK_16X input pins?

    Part Number: AFE58JD18 Unused JESD CML pins, CLK_1X, CLK_16X, NC pins can be left floating. http://e2e.ti.com/support/applications/medical/f/30/t/550784 http://e2e.ti.com/support/applications/medical/f/30/t/547048

  • [FAQ] ADS52J90: How to terminate SYNC_SERDES, SYSREF_SERDES signals in ADS52J90?

    Part Number: ADS52J90 SYNC and SYSREF pins’ termination were recently updated to the architecture below in order reduce glitches and false triggers. https://e2e.ti.com/support/applications/medical/f/30/t/585265

  • [FAQ] AFE5809: How to load the saved settings at startup in AFE5809? Will the profile ram hold the configuration values after power off?

    Part Number: AFE5809 User-defined device settings cannot be used to configure the AFE5809 at startup but specific configuration steps can be saved in a CMD file by using the GUI’s “record command” and “save command” features. http://e2e.ti.com/support…

  • [FAQ] AFE5809: How to access the coefficient memory for the filter coefficient in AFE5809?

    Part Number: AFE5809 For Coefficient memory accesses, the SPI write is different than a standard SPI write of 24 bits. It will be a single SPI cycle access of 120 bits (8 bits of address followed by 112 bits of data with MSB first) The SEN signal should…
