The PDV package is mentioned in the PCI1520PDV datasheet but the corresponding page is missing:
8 Mechanical Information
The PCI1520 is packaged in either a 209-ball GHK/ZHK BGA or a 208-pin PDV package. The following show the mechanical dimensions for the GHK, ZHK, and PDV packages.
Even on TI.com package information system there is no data available.
Can you provide the PCI1520PDV(PDV package) mechanical information?
