  • RE: HMC767: writing 1 to 02h (setting Reference Divider to 1) makes it so no SPI reads are correct


    Indeed we have a 10 ohm series resistance on SPI lines. This helped fix communication issues due to glitches and reflections on the line.

    Regarding SPI mode selection on boot up, I don't think that's the issue here, as SPI communications are restored…

  • ECG 12D ADAS : could i use 2 ADAS1000 (1 master 1 slave) instead of an ADAS1000-2

    Hi everyone,

    Because of the current component shortage, we are wondering if we can replace our ADAS1000-2 by a second ADAS1000 in order to get ECG 12D ? We tried to replace it by an ADAS1000 on an existing board but i can't get a frame from the slave…

  • ADSP SC584 SHARC+: Enabling Link Port advances it's DMA's current address by 1 word and decreases current X count by 1

    In our application we are using link ports to transfer data between an FPGA and the DSP at periodic intervals. We setup link port 1 (LP1) in DMA receive mode as prescribed in the HRM (pages 15-15, 15-16). After the data is received, LP1 and it's DMA are…

  • LTC4269-1 - EMC


    We designed a PoE using LTC4269-1 and we are experiencing some emissions problems (EMC). I would like to ask a few questions regarding to my design and the  LTC4269-1 demo board, please we need to address this issue using a private channel. 

    Thank you

  • LT3045-1 Set Capacitor


    I am using the LT3045-1 to post-regulate the output of a switching regulator.

    On page 18 and 19 of the datasheet of LT3045-1 I saw that using a ceramic capacitor at the SET pin can cause significant output noise due to piezoelectric response.
