Deserialization 12 bits LVDS in a Cyclone III

I can share a simple deserializer utilizing DDIO:

chan:
FOR I IN 0 TO 7 GENERATE
  lvds_rcv : altddio_in
  GENERIC MAP (
    intended_device_family => "Cyclone III",
    invert_input_clocks => "ON",
    lpm_type => "altddio_in",
    power_up_high => "OFF",
    width => 1)
  PORT MAP (
    datain => AD9222_D(I TO I),
    inclock => fastclock,
    dataout_h => dataout_h(I DOWNTO I),
    dataout_l => dataout_l(I DOWNTO I));
PROCESS (fastclock)
  BEGIN
    IF rising_edge(fastclock) THEN
      lvds_sr(I) <= lvds_sr(I)(9 downto 0) & dataout_l(I) & dataout_h(I);
    END IF;
  END PROCESS;
PROCESS (slowclock)
  BEGIN
    IF reset = '1' THEN
       lvds_rx(I) <= (others => '0');
    ELSIF rising_edge(slowclock) THEN
       lvds_rx(I) <= lvds_sr(I);
    END IF;
END PROCESS;
END GENERATE;
