7 Mechanical Data
The PCI2050B device is packaged either in a GHK 257-ball MicroStar BGA™, a 208-terminal PDV package, a
208-terminal PPM package, or a RoHS-compliant ZHK 257-ball MicroStar BGA™. The following shows the
mechanical dimensions for the GHK, PDV, PPM, and ZHK packages. The GHK and ZHK packages are mechanically
identical; therefore, only the GHK mechanical drawing is shown.
