New Symbols, X7602, X7601, U760, U7603, U7601

Rene Harder
Hi all,

Finally,  I have some time now to join your project.

I better start from the bottom of the TODO list then Álvaro is quite
fast creating new symbols and we don't want to do everything twice ;-) .

So here are my first contribution for review:

X7602 (CC7V-T1A) - Crystal GPS  32.768kHz
 
something easy to get used to Kicad.


X7601 (IT3205BE) -  TCXO 23.104 MHz   DRAFT!!!!

I could not find any datasheet to this particular oscillator so i used
the symbol from the gta02 schematic. It seems that Rakon redesigned
their website recently and deleted all specs for the older models. I
think the closest one is the IT3200C series. However, I'm still
wondering if the pad design of the B series is similar to the C, E and M
models (6pins 2 or 3 NC, depending on package).

IT3200C-E:
http://www.rakon.com/Products/Public%20Documents/Specifications/IT3200C-E.pdf


U7602 (R3113D241A) - Low Voltage Detector

I have some doubts with the name of pin 2. The datasheet says VDD,
however in the gta02 schematics it is named IN. I would go for IN then
this is a voltage detector and pin2 will be the input where it detects
the threshold voltage.
What do you think, any ideas?
Datasheet: http://www.ricoh.com/LSI/product_power/vd/r3113d/r3113d-e.pdf


U7603 (B7840) - Low loss RF filter for GPS receivers

I'm not quite sure what fits best to the type of the pins so i left them
passive.  We might need to change them later on.


U7601 (ATR0610-PQQW) - GPS Low Noise Amplifier
So that's the last one for today.


BTW: I added some resources to the INFO file (see attachment)

Rene

I should post my on-going stuff here often. Will do so from now on, just to avoid duplicate effort.

Excellent! I'll wait just for Werner to do first-pass review then I'll review them myself.

Well, if we do put IN as "Input", then OUT should be "Output". This output is uses as a digital reset, so this should be better.

Thanks again for your work :)

Welcome ! I've been trying to do the review today, but too many
other things got in the way, sorry. Just one quick comment:

> -P: vibrator

The idea here is that we keep the symbols and their name generic,
so it should be "vibrator". The logic in this database (INFO) is
admittedly a bit contorted, because a data sheet is often more
specific. I'll have to think a bit more about how to structure it
more cleanly.

> +D: http://www.di-motor.com.tw/html/page.html #only some specs

Great ! This is the best public information we have so far.

Thanks,
- Werner

Okay, good to know. I tried to figure out what these tags mean and in
the end i properly was misled by the header where is says P=part number.

Yeah, that one was very misleading. I changed it to "S" for "symbol"
now.

Another change: mkdsv now downloads the first data sheet, not the last
one.

In general, we should try to follow the data sheets, unless they're
plain wrong or horribly misleading. I think VDD makes sense because
it's also used as the chip's supply voltage and in the C version, it
determines the output high voltage.

GND should be Power In, not Power Out.

> +# Low Voltage Detector

That should just be the component file name, minus the .lib
More detailed part numbers can go to the top.

I made the above changes and checked it in.

Thanks !

One of the few wheels we don't need to re-invent ;)

For other directional filters, we just used Input and Output, so I
changed it accordingly. I also make GND Power In.

Thanks,

I made a few small changes:
- the RF_GND pin was off by 5 mil
- I think a non-filled triangle is more common as amplifier symbol
  than a filled triangle
- the data sheet calls pin 3 DC_GND, not GND
- changed DC_GND an RF_GND from Power Out to Power In (you had
  VCC right ! :)

Hmm, where does the "W" come from ? Didn't find it in either the BOM
nor in the data sheet. Google has a few hit, but these seem to be
sites that generate fake hits similar to the real items they have.

So I left the "W" out.

Thanks,

Okay, both ways make kind of sens to me but your are right to go with
the specs i probably the right way.

I just saw i did it wrong with all Symbols =-O .  That would cause
serious problems with the ERC.

It's not :-( The 3205BE comes in a 3.3 x 2.74 mm package, at least
that's what the drawing at the end of the data sheet says. The front
page has 3.2 x 2.5 mm. The footprints changes accordingly.

A quick search didn't turn up any publicly accessible 3205BE data
sheet either.

Besides the usual Power In vs. Out on GNS, the symbol is fine.
I've added it.

Thanks !

I think DC_GND sounds odd and does not make any sens to me. GND always
refers, if not otherwise specified (DGND, AGND etc.) to the supply
ground which is in this case DC. So I thought i reduce the redundant
information.

For other directional filters, we just used Input and Output, so I
changed it accordingly. I also make GND Power In.

Thanks,

I also find the DC_GND rather unusual. However, we try to stay close
to what the data sheet calls things and try to avoid exceptions. Cases
where there are exceptions are (I'm reiterating this for the benfit of
any newcomers):

- inverted pins or functions. There, all the different types of markup
  just become an "n" prefix.

- if the data sheet is wrong or seriously misleading

- if the data sheet is inconsistent

I think it's better to be conservative with exceptions, or we'll find
ourselves with the task of doing an overall taxonomy and nomenclature
of signal names on our hands before too long. Let's not go there ;-)

DC_GND doesn't have any of the problems above, so I'd just let Atmel
have their little quirk.
