750 MH, 16 × 8 Analog Crosspoint Switch

The ADV3224/ADV3225 are high speed 16 × 8 analog crosspoint switch matrices. They offer a −3 dB signal bandwidth of greater than 750 MHz and a high slew rate of greater than 2500 V/μs.

The ADV3224/ADV3225 include eight independent output buffers that can be placed into a high impedance state for paralleling crosspoint outputs to prevent off channels from loading the output bus. The ADV3224 has a gain of +1 and the ADV3225 has a gain of +2, and they both operate on voltage supplies of ±5 V. Channel switching is performed via a serial digital control that can accommodate the daisy chaining of several devices or via a parallel control to allow updating of an individual output without reprogramming the entire array.

The ADV3224/ADV3225 are available in the 72-lead LFCSP package over the extended industrial temperature range of −40°C to +85°C.
