AD8178ABPZ

Overview

The AD8178ABPZ is a high-speed, triple 16 × 5 video crosspoint switch matrix manufactured by Analog Devices Inc. It supports RGB and HV outputs for direct monitor driving with a bandwidth of 450 MHz and a slew rate of 1650 V/μs. The device operates on flexible power supplies of +5 V or ±2.5 V and features low all-hostile crosstalk of −82 dB at 5 MHz. It includes serial and parallel programming modes, adjustable output common-mode and black levels, and a reset pin to disable all outputs. Packaged in a fully populated 26 × 26 ball PBGA (27 mm × 27 mm), it functions within an operating temperature range of −40°C to +85°C.

Feature Summary

• Supports differential or single-ended operation with sync-on common-mode and sync-on color modes
• Features independent output buffers that can be placed into a high impedance state to create larger arrays
• Offers both serial and parallel programming modes for the switch array configuration

Applications

• RGB video switching
• KVM systems
• Professional video applications

Procurement Notes

Verify component authenticity through official manufacturer channels or authorized distributors. Confirm the specific ABPZ suffix matches the required package and temperature grade. Check for obsolete status as indicated in documentation. Ensure proper ESD handling during installation due to the fine-pitch PBGA package.

Selection Notes

Select this component when a large, nonblocking switch array is required for professional video routing. Consider its compatibility with AD8175, AD8176, and AD8176 if pin compatibility is needed. Evaluate power supply flexibility requirements between +5 V and ±2.5 V configurations before finalizing the design.

Part Context

The AD8178 belongs to Analog Devices' family of high-speed video crosspoint switches. It is designed to support 1600 × 1200 RGB displays at 85 Hz refresh rates. The device provides excellent ac performance with low crosstalk and isolation, making it suitable for demanding signal conditioning tasks in professional video environments.

Replacement Considerations

The AD8178 is pin compatible with the AD8175, AD8176, and AD8177. Verify functional differences such as switch array size (e.g., 16 × 9 for AD8175/AD8176) before substituting.
