Minutes of the weekly Beetle and OTIS meeting (BOM) on  29.11, 14:00

Participants:
        M. Schmelling, D. Wiedner, S. Loechner, H. Deppe, U. Stange, D.
        Baumeister

OTIS:
====
        + DNL
          there exist up to now non-consistant figures:
          0.47 for an input pulse width of 1.6ns
          0.85                             3.6ns

          this has to be clarified

          the biggest perturbation occurs at channel 6/7 and channel
          14/15/16 for both pulse widths

          further investigations will be done by Harald/Dirk

          present work:
          Uwe:    verilog programming
          Harald: layout of DLL/hit registers
          Dirk:   preparation of straw tube chamber test at HERA-B,
                  preparation of OTIS tests (derandomizing buffer on
                  BeetleSR10)

        + to be included in OTIS spec:
          - "DataValid" signal
          - data format: no data corresponds to logic 0

Beetle:
======

        + LHCb week rehearsal (Daniel)
        + pipeline gain uniformity is still under investigation (Daniel)
        + further noise measurements are under way (Daniel)
        + design work for Beetle1.2 started: new protection diodes at
          analog input (Sven)
        + noise measurements on BeetleFE1.1 have to be done/analysed
          (Sven)
