GENERAL DESCRIPTION
The ADV3228/ADV3229 are high speed 8 × 8 analog crosspoint
switch matrices. They offer a 3 dB large signal bandwidth of
750 MHz (ADV3228) and a slew rate of 2500 V/μs.
The ADV3228/ADV3229 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 ADV3228 has a gain of +1, the ADV3229 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 daisy chaining of several devices or via a parallel
control to allow updating of an individual output without
reprogramming the entire array.
The ADV3228/ADV3229 are available in the 72-lead LFCSP
package over the extended industrial temperature range of
40°C to +85°C.
