AD8178 is a high performance video crosspoint switch from Analog Devices. It has a 16x5 array, supports differential or single-ended input, supports 450MHz bandwidth, 1650V/μs slew rate and 4ns settling time.
The AD8178 is a high‑speed triple 16 × 5 video crosspoint switch matrix designed for RGB video switching, KVM, and professional video applications. It offers a 450 MHz bandwidth, 1650 V/µs slew rate, and low crosstalk (‑82 dB at 5 MHz) in a fully populated 26 × 26 ball PBGA package.
The device supports both differential and single‑ended operation, serial or parallel programming, and flexible supply voltages of +2.5 V or +5 V. It operates over an extended industrial temperature range (‑40 °C to +85 °C) and includes features such as output disable, adjustable output common‑mode, and high‑impedance output states for array expansion.
