The ADV3200/ADV3201 are 32 &TImes; 32 analog crosspoint switch matrices. They feature a selectable sync-TIp clamp input for ac-coupled applicaTIons and an on-screen display （OSD） inserTIon mux. With −48 dB of crosstalk and −80 dB isolation at 5 MHz， the ADV3200/ADV3201 are useful in many high density routing applications. The 0.1 dB flatness out to 60 MHz makes the ADV3200/ADV3201 ideal for composite video switching.
The 32 independent output buffers of the ADV3200/ADV3201 can be placed into a high impedance state for paralleling cross-point outputs so that off channels present minimal loading to an output bus if building a larger array. The part is available in a gain of +1 （ADV3200） or +2 （ADV3201） for ease of use in back-terminated load applications. A single 5 V supply， dual ±2.5 V supplies， or dual ±3.3 V supplies （G = +2） can be used while consuming only 250 mA of idle current with all outputs enabled. The channel switching is performed via a double buffered， serial digital control， which can accommodate daisy chaining of several devices.
The ADV3200/ADV3201 are packaged in a 176-lead exposed pad LQFP （24 mm × 24 mm） and are available over the extended industrial temperature range of −40°C to +85°C.
