Hi Attila,
" Unfortunately, since they redesigned their webpages, i cannot find the
OCXOs listed anywhere anymore (only the 8607 shows up)."
Oscilloquartz has discontinued their OCXO line. The only exception is the
BVA OCXO.
Best regards

...and, all of their products that use OCXOs?

I'm thinking of doing a breakout board similar to this one
http://bit.ly/1buC4ZD for the subject Maxim chip.
"Why?" you may ask. Unlike many other RTC chips, this one supports a 1 PPS
drive. The specs are here http://bit.ly/1eE5vh1 on the Maxim site. There
seems to be considerable interest in driv

You want to drive the RTC with an external PPS to get time/date into an Arduino?
Why not feed the PPS to the Arduino and have it compute date and time?
It is really not that hard to count seconds. You don't really need an external
chip to do that.

Good job! I've read other good experiences about the Beiming. I finally wound
up buying a Prologix Ethernet adapter. Let this be a warning to anyone who is
tempted to buy the 82357B clone with the gold-anodized aluminum case. Do Not

Hi Mark,
Well, his subject is "linux-gpib", and the gold anodized clone simply will not
work with the linux-gpib drivers. I think I drove the developer batty trying
to get it to go, but it's not going to happen without a complete rework of the
code. I don't know whether that will ever take pl
Hi Didier,
True this could be done in SW, and I should have mentioned that I
considered that in my post. However, these chips offer several other
functions that would add complexity to the code, and I've been looking for
a reason to do a simple HW project and open source it through OSH Park
anyway
Hi
In volume a 32KHz crystal is a sub 5 cent item. In high volume very sub 5
cents. The RTC chips are *way* more expensive.

Typically you need mor
Because the 32Khz xtals are profoundly cheap and accurate to some extent.
Long divide by 2 chain is very simple. The xtal could be easily adjusted
close to the correct frequency. It all sort of came from watch technology.

Many times the 32KHz oscillator is just used for ultra-low power rudimentary
CPU timing, not so much for a "time of day" clock. The crystal gives more
reliable timing than an RC delay, and the low power works fine for a "press to
wake up" type application.

I've got a question for you Hal. We can take it offline if it's more than a
response or two. I opened two sockets to the adapter in one program and found
the same socket id. OK, that tells me that I have to address each device
before sending commands to it, rather than having a separate socke
Hi Russ,
I will venture that the vast majority of applications are served with 2 pins
and a $0.10 crystal rather than the external silicon implied by a 1Hz input.
The advantage of off-chip timekeeping is the low power consumption of dedicated
RTC chips that makes them able to run from a coin ce
Prologix Ethernet controller supports only one client connection. A second
connection will disconnect the first one. Make sense, since a GPIB bus can
have only one (active) controller. Currently, the controller does not allow
a client to lock it exclusively, since that opens up the issue of orphane
