AD8176ABPZ

Overview

The AD8176ABPZ is a high-speed, triple 16 × 9 video crosspoint switch matrix designed for professional video applications. It supports 1600 × 1200 RGB displays at an 85 Hz refresh rate, featuring a 450 MHz bandwidth and a 1650 V/μs slew rate. The device operates with flexible power supplies of +5 V or ±2.5 V and draws 600 mA per supply rail when outputs are enabled. It offers low hostile crosstalk of −82 dB at 5 MHz and −47 dB at 500 MHz. The component is packaged in a fully populated 26 × 26 ball PBGA (27 mm × 27 mm) and functions within an operating temperature range of −40°C to +85°C.

Feature Summary

• Supports differential-in to differential-out operation with selectable sync-on common-mode signaling passing through the switch or being removed.
• Features independent output buffers that can be placed into a high-impedance state to facilitate larger arrays by paralleling crosspoint outputs.
• Allows adjustable output common-mode voltage and black level via external pins for direct monitor driving using decoded H and V outputs.

Applications

• RGB video switching
• KVM systems
• Professional video

Procurement Notes

Verify the obsolete status of this component before procurement. Confirm availability through authorized distributors or secondary markets. Ensure the package matches the 26x26 ball PBGA specification. Check for RoHS compliance if required by local regulations. Validate the specific ABPZ suffix against the manufacturer's ordering guide for any functional variations.

Selection Notes

Select this component for designs requiring a large non-blocking switch array with high bandwidth. Ensure the system accommodates the 3.5 W power dissipation and thermal requirements of the PBGA package. Verify compatibility with serial or parallel programming modes for the control interface. Consider the wide input common-mode range and output drive capabilities for signal integrity.

Part Context

The AD8176 is part of Analog Devices' video crosspoint switch family. It is pin-compatible with the AD8175 (16 × 9), AD8177, and AD8178 (16 × 5). This compatibility allows for design flexibility and potential migration between different channel counts without changing the footprint.

Replacement Considerations

The AD8175 is a pin-compatible alternative offering a 16 × 9 switch array. The AD8177 and AD8178 provide 16 × 5 configurations and are also pin-compatible. Verify electrical specifications and application requirements when substituting these models.

FAQ

What is the maximum refresh rate supported for 1600 × 1200 RGB displays?

The AD8176 supports a refresh rate of 85 Hz for 1600 × 1200 RGB displays.

How does the device handle common-mode signals?

It supports two modes: differential-in to differential-out with sync-on CM signaling passed through, or with CM signaling removed through the switch.

What is the typical crosstalk performance at 500 MHz?

The all-hostile crosstalk is typically −47 dB at 500 MHz.
