Actually the Jameco function generator uses the XR2206 hence the
partnumber JE2206.
 
I've been playing more with the Maxim MAX038 tho.  It seems to have much
better low frequency stability then the Exar.
Both of them have been around for well over a decade
so I almost consider them "Safe" to use.  I personally try not to use
odd parts that might dissappear like the CEM chips did.

I personally wouldnt both with the Jameco kit. The board is very large for
what they've put on there and I had to do alot of parts changes to make it 
into a decent LFO.  Its almost as easy to just buy the chips, download the
datasheets, and roll your own.

A note on Jameco: They are a wee bit pricey.  I use them alot because they're
located about 4 miles from work.  Of course, my other close choice is Frys
but the less said the better *sigh*.
You might want to scope out JDR Microdevices ( www.jdr.com ) they are down
in San Jose, and ship as fast as Jameco and sometimes are cheaper.
