TYPICAL CIRCUIT CONNECTION
Examples of how to connect the 40-lead LFCSP, 64-lead LQFP, 48-lead LQFP, and 32-lead LFCSP video decoders are shown in Figure 55,
Figure 56, Figure 57, and Figure 58. For a detailed schematic of the ADV7180 evaluation boards, contact a local Analog Devices field
applications engineer or Analog Devices distributor.
