    BNO085 - Bringup

    Hello, I tried to breakout the BNO085. I used a known good design from Adafruit (attached the schematic). Now unfortunately it doesn't work. I written software for the Adafruit board and it works fine. Then I replaced the Adafruit board with my breakout board ("schematic_not working" in the...

    Need help with Crystal Oscillator circuit...

    Hi, I need the simplest circuit to run 250 crystal oscillators at once. The circuit must give a sharp pulse to all the crystals at 1Hz. The idea is the get them all "ring" and resonate with each other. They are regular 32khz cylinder oscillators used in watches. Any ideas?

    Clocking a HI7190 ΣΔADC using a 10MHz Quartz Crystal Oscillator

    Hello, This is my first post so I'm sorry ahead of time if I'm missing key information. I am trying to produce a clock signal for a HI7190 (ΣΔADC) using a 10MHz quartz crystal oscillator. The HI7190 uses either 2-Wire or 3-Wire (SPI-compatible) communication for reading and writing internal...

    Need to explain about principle of comparator based crystal oscillating circuit.

    Hi everyone, I am a newbie in electronic field. Now I am trying to design a circuit to drive QCM (Quartz crystal microbalance). In some literature I have seen some comparator-based designs like this: In fact, some similar designs can also be found in the datasheets of high-speed comparators...
