The ADV3200/ADV3201 are 32 × 32 analog crosspoints
Switch matrixwith optional sync pulse top clamp input for AC-coupled applications, as well as on-screen display (OSD) insertion
Multiplexer。 Both devices have -48 dB crosstalk performance and -80 dB (5 MHz) isolation, making them suitable for many high-density routing applications. At the same time, the 0.1 dB flatness of 60 MHz is ideal for composite video switching applications.
The ADV3200/ADV3201 contain 32 independent output buffers that can be placed in a high impedance state to provide parallel crosspoint outputs, so when building larger arrays, the shutdown channel provides minimal load to the output bus. The ADV3200 provides a gain of +1 and the ADV3201 provides a gain of +2 for back-terminated load applications. Both devices can operate from a single 5 V supply, dual ±2.5 V supply, or dual ±3.3 V supplies (G = +2), and the idle power consumption is only 250 mA with all outputs enabled. The channel switches are implemented through a double-buffered serial digital control interface that can be used to daisy-chain multiple devices.
The ADV3200/ADV3201 are available in a 176-lead exposed pad LQFP (24 mm × 24 mm) package and operate over the extended industrial temperature range of −40°C to +85°C.
