2 hsd cards can talk to 1 data card, and each data card has 4 LR4 transceivers (2 per hsd-card). hsd card has a "mezzanine" component with analog input connectors, and a JESD connection through the usual xilinx MGT (serial connection) to a pcie carrier card. There is a cable (small coax cables that Matt says have failed in the past) that connects the hsd card(s) (up to two) to the data card. The FPGA is on the hsd pcie carrier card.
