Product Details
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 dB of crosstalk and −80 dB isolation at 5 MHz, the ADV3202/ADV3203 are useful in many high density routing applications. The 0.1 dB flatness out to 60 MHz makes the ADV3202/ADV3203 ideal for both composite and component 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 back-terminated load applications. A single +5 V supply, dual ±2.5 V supplies, or dual ±3.3 V supplies can be used while consuming only 195 mA of idle current with all outputs enabled. The channel switching is performed via a double buffered, serial digital control, that can accommodate daisy chaining of several devices.
The ADV3202/ADV3203 are packaged in a 176-lead exposed pad LQFP package 24 mm × 24 mm and are available over the extended industrial temperature range of −40°C to +85°C.
