The TLG GPIP is based on the commercially available General Purpose IndustryPack Module from BIRA Systems. It is used to delay signals used to generate Booster, Main Injector and Tevatron TCLK reset events and also events $08 and $1A.
The TLG GPIP is also used to read the status of the "NTF Priority Request" line.

Another feature of the TLG GPIP module is that it can be used to transmit a single MDAT frame. This feature is no longer used as the frames are sourced from an 8 Frame MDAT Transmitter GPIP module
