There is no page 53 of the manual, as the pages themselves are labeled.
Acrobat labels the pages differently, so i'm guessing you mean Acrobat's
page 53, which is actually page 49 of the document.
That page seems to be 4 serial data level translators and an FPGA.
A square on a schematic with an FPGA is not going to do you much good,
either, without the configuration information for the FPGA. The interface to
the analog scales is actually on the next page, where it shows the 15-pin D
connectors with the SIN+/SIN- and COS+/COS- signals going into an
op-amp. But, that's all there is on that page, and that is a FAR cry from an
interpolator.
