AD8175
Obsolete500 MHz, Triple 16 × 9 Video Crosspoint Switch
Part Details
- High channel count, triple 16 × 9 high speed, non-blocking switch array
- Differential or single-ended operation
- Supports sync-on common-mode and sync-on color operating modes
- Decoded HV sync outputs available

- Flexible power supplies: +5 V or ±2.5 V
Logic ground for convenient control interface - Serial or parallel programming of switch array
- High impedance output disable allows connection of multiple devices with minimal loading on output bus
- Adjustable output CM and black level through external pins
- Excellent ac performance (to support 1600 × 1200 @ 85 Hz)
Bandwidth: 500 MHz
Slew rate: 1800 V/μs
Settling time: 4 ns to 1% - See data sheet for additional features
The AD8175 is a high speed, triple 16 × 9 video crosspoint switch matrix. It supports 1600 × 1200 RGB displays @ 85 Hz refresh rate, by offering a 500 MHz bandwidth and a slew rate of 1800 V/μs. With −88 dB of crosstalk and −94 dB isolation (@ 5 MHz), the AD8175 is useful in many high speed video applications.
The AD8175 supports two modes of operation: differential-in to differential-out mode with sync-on 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 independent output buffers of the AD8175 can be placed into a high impedance state to create larger arrays by paralleling crosspoint outputs. Inputs can be paralleled as well. The AD8175 offers both serial and parallel programming modes.
The AD8175 is packaged in a fully-populated 26 × 26 ball PBGA package and is available over the extended industrial temperature range of −40°C to +85°C.
