Currently our carrier employs an Altera MAX3000 3064ATC100 CPLD, which is
connected to the data bus and uses CE4 to select it, this PLD comes
pre-programmed to control an LCD, keypad, and some GPIO lines, but could
certainly be reprogrammed. I believe Altera has VHDL plug-ins for Quartus,
but I'd have to look it up. I was thinking about replacing it with a new
MAXII CPLD on the new rev, but I don't know much about the new line yet I'm
attending the web conference on the 31st.


It would be nice if the MMC interface also supported SD cards.
This allows adding a security interface using the hardware
secure locking of the SD card.
I'll look into this.

A much smaller size sockets board, maybe near the size of the
DS400 and powered from the Ethernet drop allows many applications.
Also a good idea, thanks!

Adding the TI TLV320AIC26 audio codec uses few pins, little board area,
and has audio A/D D/A with many sample rates.
Sounds promising, I'll look into it.

Thank you for your input,
NZG.

I'm going to do another rev of the EMAC ds400 carrier soon and I'm looking
for good ideas to add to it. One sure thing we are going to add is a one
wire jack instead of the header. I'm also considering putting some kind of
netcam header on there, I know work has already been done in this area. Is
anyone willing to share that work or is it all proprietary?

Anybody have any other suggestions out there?
What would you like to see on a board?
