GENERAL DESCRIPTION
The ADV3200/ADV3201 are 32 × 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.
