http://www.amazon.com/Linear-Circuit-Handbook-Engineering-Devices/dp/0750687037 I highly recommend that book. It's extremely practical. Unlike most electronics books that can't say anything truly meaningful without slipping into differential equations, this keeps everything at a very accessible level. They specifically address the issue that appnotes always design simple, single mixed-signal device PCBs and give no hint as to how to expand that to a multi-chip design. If you 'search inside' for 'split' and take the link that starts at page 873 you might be able to get what you want. -- Ben Jackson AD7GD <[EMAIL PROTECTED]> http://www.ben.com/ _______________________________________________ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
