I had OKI send to me the rough data sheets on the 6242 when I called
to ask questions about the MSM58321 (note the '1' opposed to the 
MSM5832 chip).   OKI is the only company I know of that has a toll
free 800 number that you can call and the engineer of the chip is
happy to answer your questions and help you use his chip in your
application!!!   I was most impressed.

However, I chose to continue to use (once I got it working properly
after the phone call...) the MSM58321 (16-pin with on-chip auto-leap-
year).  The 6242 is a much faster chip, is 18-pin (I HATE 18-pin
chips...), is more expensive, and I can not get a low quanity supplier
of it.   Since I am set to control the clock/cal chip from the I/O
ports of my sound chips in my application anyway, the 58321 was my
perfect choice!   

I was most impressed with all the OKI clock/cal ICs, their support
and if you want a truely remarkable experience: walk into the OKI
front lobby in Silicon Valley in Sunnyvale and see their new building.
The very large and tall lobby is all stainless steel (well, it looks
like stainless steel, may not be...)!!!

Cheers,
