Branded datatrak S0089-1, but fab by TI as CF30192.
Based on date and die markings, this appears to be a Texas Instruments TGC100 or similar gate array.
Removed from a Datatrak “Mk.II” navigation receiver. Includes 68000 glue logic (address decode, DTACK, etc.) and a digital phase comparator. The phase comparator is used to receive phase-modulated data and measure the phase of the navigation bursts against a 20MHz TCXO built into the nav receiver.
