TI 751979BIZ Digital Baseband Processor (DBB) [PNG]

This is a Digital Baseband Processor designed by Texas Instruments in 2004. It was most likely contained in a Sony Ericsson Z520a cell phone.

 

This chip was incredibly difficult to identify, I only had portions of the main board and google did not return anything immediately. The only thing I was able to find which documented this chip was this page:

electronics360.globalspec.com/article/3300/sony-ericsson-...

 

It says:

"DBB - Digital Baseband Processor - Texas Instruments - 751979BIZ"

 

As far as I can tell this chip has no publicly available data sheet.
