It's at the Documents section at VLSI webpage: http://www.vlsi.fi/en/support/download.html

File name: VQFN68_DG8787_Rev_A.PDF.

At the same page, you can find Eagle libraries for VLSI components.

Eagle is free to use for viewing the libraries and designing small boards. We don't use Protel because of the cost.

In practice, the VS1010 package has proven to be very good and much easier to solder than VS1005. Just make sure you don't route anything in the 2nd row exposed pads area, except ground connections to the center pad area.

Hello

VS1010 component has been added to the Eagle 7.6 EDA library at:
http://www.vlsi.fi/en/support/download.html
-> vlsi_eagle7_lib.zip
Normally you should use the -Q / QFN68 variant of the package,
it contains the recommended ground wiring and via placement.
Eagle DRC will generate 8 errors from the package, please
ignore them.

The -QP / QFN68P variant should be used only if you need to
change the placement of the ground vias. Not recommended.
