df071c3398 New ECN about clock circuit of atusd boards. Measured (absence of) effect of
adding an inductor to the clock line.

- ecn/INDEX, ecn/ecn0005.txt: new ECN discussing the switch to a
  capacitative clock voltage divider. With frequency measurements.
- atusd/tests/send-20100910: measurement of transceiver performance when
  placing an inductor in the 16 MHz clock line.

b32827dc7e Oops. The atusb boards are of course 20100813. 20100902 was the first
(failed) attempt to make an atusd board.

0a0a50d73d Performance comparison of atusb vs. atusd.
- atusd/tests/send-20100909: conducted performance comparison of atusb vs.
  atusd

6e726d1fb9 Improved clock stability by using a capacitative divider and found more minor
issues.

- atusd/ERRATA: work around the clock instability by replacing the
  resistive divider with a capacitative divider
- atusd/ERRATA: a ground plane under the clock circuit would also be good to
  have
- atusd/ERRATA: via near pin 1 is too close to the chip if we need to cut
  wires (in DIY boards)
- atusd/sim/cdiv.sch: simulation of the capacitative divider

93f0f403a7 New atusd errata and a few small CAM updates.
- atusd/ERRATA: added errata section for version 20100908
- atusd/cam/doit: increase tool clearance from 1.5 mm to 2 mm
- atusd/cam/pcb.pl (cut): cutting counter-clockwise did not reduce burr.
  Removed reversal of cutting direction.
- atusd/cam/pcb.pl: made area selection formulas easier to understand

3533e0463c Found out that we can't share MISO and MOSI after all. Redesigned the atusd
board.

- atusd/atusd.sch, atusd/atusd.brd: separate MISO and MOSI and free the
  extra signal we need by no longer connecting SLP_TR to the host
- atusd/atusd.sch, atusd/atusd.cmp, atusd/atusd.brd: removed reset circuit
  Power-on reset seems to be sufficient.
- atusd/atusd.brd: improved AVDD ground plane
- cam/pcb.pl (rot): cut counter-clockwise to reduce burr
- cam/pcb.pl: advanced origin for 2nd run

  place coverage

7c1383d43e Added components (transistor and balun) for the uSD variant.
- atusd/Makefile:
- AUTHORS, atusd/Makefile, atusd/dtc123.lib, atusd/dtc123je.fpd: borrowed
  the DTC123 symbol (Alvaro Lopes) and footprint (Dave Ball) from
  gta02-core. Note that this isn't the part I'm using in my prototype, and
  I'm trying to get rid of it entirely, so all this will change before too
  long.
- components/BOOKSHELF, components/INFO, components/balun.lib,
  modules/Makefile, modules/INFO, modules/0805-6.fpd: added the Wuerth
  748421245 balun
