GENERAL DESCRIPTION The ADV3202/ADV3203 are 32 × 16 analog crosspoint switch matrices. They feature a selectable sync-tip clamp input for ac-coupled applications and a 2:1 on-screen display (OSD) insertion mux. With - 48 d B of crosstalk and - 80 d B isolation at 5 MHz, the ADV3202/ADV3203 are useful in many high density routing applications. The 0.1 d B flatness out to 60 MHz makes the ADV3202/ADV3203 ideal for both posite and ponent video switching. The 16 independent output buffers of the ADV3202/ADV3203 can be placed into a high impedance state for paralleling crosspoint outputs so that off-channels present minimal loading to an output bus if building a larger array. The ADV3202 has a gain of +1 while the ADV3203 has a gain of +2 for ease of use in...
