Mike,
Welcome to the TI E2E forum. I hope you will find many good answers here and in the TI.com documents and in the TI Wiki Pages. Be sure to search those for helpful information and to browse for the questions others may have asked on similar topics.
A bit tounge-in-cheek, but if you can wait until September and we can convince my boss to fly me across the country, my son will be at UCSD and I would be happy to come for a visit.
You might want to take out the last line since this forum is visible to anyone on the web, but then I may jsut be overly reserved about those things.
You will have better luck getting someone by calling the local TI Sales Office or by calling your favorite Distributor, depending on your company's business relationships with TI and the Distributors. And of course a look through TI.com should help you understand some of our offerings, especially the Applications tab and the Consumer & Portable Electronics area.
The C6748 and AM3359 are parts that come to my mind. But someone more familiar with what you are doing would give you a better suggestion.
Regards,
RandyP
