300 MH, 32 × 32 Buffered Analog Crosspoint Switch

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 crosspoint outputs so that off-channels present minimal loading to an output bus if building a larger array. The part is available in 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.
