   quick diagram of the resistor array, a 4816P-B07-000. the comparator output goes to pins 1, 3, 5, and 7. pins 2, 4, 6, and 8 are grounded (so the 670 ohm resistors go to ground). the outputs to the FPGA seem to be on pins 10, 12, 14, and 16. the remaining pins go...elsewhere. i suspect it's some sort of termination network that might do some level shifting. perhaps the comparators have ECL outputs or something.
