I doubt there is any limitation that prevent LIBM to be used in driver
code.
Are you sure the math.h included is the math.h from eCos?
Could you provide all includes you have in this driver and the C code
that uses the log function ?

Hei Rune,
So, where is the error? PN should be 110368 and not 110338?

2010/11/15 Rune O Alexandersen <rune.alexander...@creodev.no>
Hei!
It took some time to go thru all, but I found one fault:
- PN 110338. Reduce quantity from 4 to 3. Remove R390,R391. Add R1151
Should be: - PN 110368. Reduce quantity from 4 to 3. Remove R390,R391. Add R1151

Hei,
Sure. I have changed C621 to 0p5. I have not stepped the revision in the
documents. I have not added the change to the revison list, perhaps someone
else can do so.

Then I suggest we also include this change in rev 2.1.
I was just working on storing and completing all documentation here ....
Any chance you could add this change early Monday morning Svein?

Hei igjen!
I just discovered that the new modulator emits more 3 and 5 harmonics than the
old one (and less 2 harmonics).
3 harmonic of 1,1GHz was just -28dBc at the output.
This could be fixed with a small change in the output filter.
C621 changes from 1pF to 0p5.
All the harmonics now stays below -36dBc.

Hei Rune,
Her is updated SL2900 rev P2_1C. It should be correct according to enclosed
last version of 2.1 changes. Could you take a final check?

Hei!
Bra!
Fotavtrykket til R346 skal fremdeles være 0603.
Det er egentlig en spole. Jeg trengte ca 1,2nH og det tilsvarer omtrent en
seriekobling av en 0603 og en 0402 komponent.
Oppdaget en liten feil:
R646 skal være 10R
C641 skal være 33p

Vel, ja. Det var måleresultatene etter at endringene var innført.
Mest som info til Christophe.
Kan sende som zip og se om det går da.

Svein,
We are now close to finalising SL2900 and SL2901 BOMs and I'm ready to
schedule more boards for production.
Regarding the BOM / schematic I have following plan:
1. SL2900: Update schematic & BOM to Rev 2.1: Used to manufacture next
13 boards as soon as possible => Can you update schematic by end of week
after coordinating with Rune?
2. SL2900: Update schematic and PCB to Rev 3.0. Change version
resistors + few layout changes to improve manufacturability. To be completed
next week
3. SL2901: Final BOM Rev 3.0 to be completed and sent to customer
during next week.
Are you able to handle this and coordinate as needed with Rune & Ole Jacob?
Regards,
Helge
