xggg | Domino wave | Hi Stefan,
According to the datasheet DRS_rev09,
the write signal is always 16 cells wide. |

Stefan Ritt | Domino wave | Look at the attached picture. For simplicity,
only 4 cells are open and tracking the input
signal. Time is flowing from top to bottom. |

Volodymyr Rodin | Driver installation on Windows 10 | Dear Laura
You need to disable driver signature
enforcement. Then try again with path |

the drs4 start to generate Dtap
signal after reset and standard configuration. |

Stefan Ritt | Dtap stops toggling after 40msec | No idea what you do wrong. I need to see
oscilloscope traces for all your inputs and
voltages. What is your REFCLK input? |

mony orbach | Dtap stops toggling after 40msec | my refclk is 1.25Mhz
what are the inputs and voltage
you need to see? |

Stefan Ritt | Dtap stops toggling after 40msec | I want to see the trace on the scope for
the DTAP, the REFCLK, the DENABLE and the
DWRITE. |

Stefan Ritt | Dtap stops toggling after 40msec | Thanks for posting the plots. It really
looks like the PLL is not working. I see
two possible reasons: 1) The PLLEN bit in |

Stefan Ritt | Dynamic Range Evaluation Board and Software | You cannot go below -0.5V for the inputs,
since the board does not have an internal
negative power supply, which would be necessary |
