Product Details

The AD8175 and AD8176 are high speed, triple 16 × 9 video crosspoint switch matrixes with a gain of 2 and 4, respectively. Both the AD8175 and AD8176 support 1600 × 1200 RGB displays at a 85 Hz refresh rate. The AD8175 has a 500 MHz bandwidth, 1800 V/μs slew rate, −88 dB crosstalk, and −94 dB isolation (at 5 MHz). The AD8176 has a 450 MHz bandwidth, 1650 V/μs slew rate, −82 dB crosstalk, and −90 dB isolation (at 5 MHz).

The AD8177 and AD8178 have the same specifications as the AD8175 and AD8176, respectively, but are 16 × 5 video crosspoint switch matrixes.

The AD8175, AD8176, AD8177, and AD8178 support two modes of operation: differential in to differential out mode with sync on common-mode (CM) signaling passed through the switch, and differential in to differential out mode with CM signaling removed through the switch. The output CM and black level can be conveniently set via external pins. The outputs can be single ended in conjunction with decoded H and V outputs to drive a monitor directly.

The independent output buffers of the AD8175, AD8176, AD8177, and AD8178 can be placed into a high impedance state to create larger arrays by paralleling the crosspoint outputs. The inputs can also be paralleled. The AD8175, AD8176, AD8177, and AD8178 offer both serial and parallel programming modes.

The AD8175/AD8176/AD8177/AD8178 are packaged in a fully populated, 26 × 16 ball PBGA package and are available over the extended industrial temperature range of −40°C to +85°C.

The user guide UG-890 provides all of the supporting documents for evaluating the AD8175/AD8176/AD8177/AD8178 using the AD8175-EVALZ/AD8176-EVALZ/AD8177-EVALZ/AD8178-EVALZ evaluation board. Additional information is available in the AD8175, AD8176, AD8177, and AD8178 data sheets, which should be consulted in conjunction with UG-890 when working with the evaluation board.
