f33b86b317 atusb.brd: reduced XTAL front ground to shorted "tongue" between pads 24 and 25 2010-12-29 18:51:01 -03:00

cec090f7b2 atusb.brd: more layout cleanup to improve solderability
Traces leaving a pad on the side may invite solder bridges to "false pads"
exposed at the edges of the chip, with unknown consequences.

- atusb.brd: make trace from P0.0 (IRQ_RF) leave pad at the front, not
  at the side
- atusb.brd: make trave from P0.7 (SCLK) leave pad at front, not at the
  side

6f956290c3 atusb/cam2/mkmk: double backslash to put into generated makefile
With one backslash, the newline was removed, so it still worked. It just
looked odd.

7514fa8400 atusb.brd: added via from nRST/C2CK, to allow for addition of pull-up

  nRST and VDD within reach (pull-up suggested by Joerg Reisenweber)
- atusb.brd: increased version to 20101229

  another

40d1234bf4 usrp: try to bring back sanity to pre- and post-processing of FFT data
The pre- and post-processing of FFT data was tweaked based on results
obtained from a mis-configured measurement setup, in an only partially
successful attempt to right the wrong data.

- usrp/fft.c (fft_complex): square the magnitude on output but don't
  square the scaling
- usrp/fft.c (fft_real): square the magnitude on input (does this make
  sense ?)
- usrp/fft.c (fft_real): scale the output with the square root of the
  FFT size (dubious)

23c37261b7 atusb: use 0402 as the preferred component size and replace bad TVS
We know from CNTR that the capacitance of the 0603 TVS (EPCOS CT0603M4G,
200 pF) is too large and can disturb the USB signal. The 0402 TVS
(Panasonic EZJ-P0V080GA, 100 pF) works much better.

Since we have lots of 0402 components already, just change the remaining
0603 to 0402, too.

- usb.sch (VR1, VR2, VR3): change from 0603 to 0402 and from 5V5 to 5V6
- usb.sch (C1, C2, R1): change from 0603 to 0402
- atrf.sch (R3): set footprint to 0402
- atusb.pro: replaced modules/mini-usb with modules/usb_a_plug
- atusb.pro: removed extension from components/balun-smt6.lib
- atusb.cmp: update footprints for above changes
- atusb.cmp: change 0402 to 0402-M and 0603 to 0603-M, for easier
  soldering

for better mechanical stability.

- atusb.pro: change from components/mini_usb_b to components/usb_a_plug
- usb.sch (CON1): replace MINI_USB_B with USB_A_PLUG

ee6c945db9 atusb: shrink C2 pads to test point size
