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 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.

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 (G = +2) 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 16 independent output buffers of the ADV3202/ADV3203

can be placed into a high impedance state for paralleling cross-

point outputs so that off-channels present minimal loading to

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.
