This is what happens when I open the last file you sent (if_filterkr2.brd):
First, I get a warning (don't know if this is relevant):
**broken link removed**
Then I click OK and this is what the board looks like:
**broken link removed**
Then I click on Ratsnest and this is the result:
**broken...
Hum... maybe it's something with Eagle options, because this is how your file appears here:
**broken link removed**
If I click in the Ratsnest icon, Eagle will fill the polygon with copper except around the text, while the letters are written with copper.
What I wanted was something like...
I want to right the text on the upper side, not were I draw the rectangles. Anyway, I cleared the rectangles, design a polygon all around the board, write the text in the 41tRestrict layer, then click on Ratsnest and... same thing happen. The text is writen with copper while copper is cleared...
That is exactly what I want...
I am doing that this way:
- Limit the area with the polygon tool, then click on Ratsnest (the area is then filled with copper)
- Choose the 41tRestrict layer, choose the text tool, write what I want and then place it in the area where I drawn the polygon (the text...
Thanks for the quick reply.
Unfortunately that doesn't work. When I do that, and then click on Ratsnest, the text appears writen with copper, and around the text the copper is cleared, and I want the opposite, maintain the copper around the text and clear the copper to form the letters.
Hi, I have a question about Eagle software.
I want to write text in a board, but I don't want to write with the metal (or tracks), I want the opposite. That is, I want to clean the metal were the characters will be, and the text will be readable because it has metalization around. Was I clear...
Do you think the LTC6908-1 from Linear Technology is better than the 555 timer?
Is more expensive, but the 555 timer work to 3 MHz (maybe 5MHz) the most, and this LTC6908-1 can go to 10 MHz, so I would have better working margin, if the synthesizer doesn't respond well to 2 MHz input reference...
I will use a 555 timer with a Vcc=+3.3V (the same Vcc for the synthesizer). It has CMOS levels so I will be able to connect directly the output of the 555 to XIN pin.
The only thing I see that I have to be carefull is the oscillation frequency, because the synthesizer has a minimum of 2 MHz...
So, are you saying I should use a clock generator to feed the XIN input? I will choose one that works with +3V (or +3.3V) since that is the voltage I will use for the synthesizer.
Hi,
I have a very basic question, I think... I have a Synthesizer (Silabs si4136) and I want to connect this crystal oscillator (CX49GFWB) to provide the reference frequency.
How should I connect the crystal to the synthesizer? One pin from the crystal connects to XIN pin of the synthesizer and...
