AD8175ABPZ

Overview

The AD8175ABPZ 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 with a 500 MHz bandwidth and a slew rate of 1800 V/µs. The device features low all-hostile crosstalk of −88 dB at 5 MHz and −46 dB at 500 MHz. It operates on flexible power supplies of +5 V or ±2.5 V, consuming 3.5 W. The component includes decoded HV sync outputs, adjustable output common-mode and black levels, and supports both serial and parallel programming modes.

Procurement Notes

Verify the specific ABPZ suffix against the manufacturer's ordering guide to confirm package type and temperature range. Ensure the design accounts for the fully populated 26 x 26 ball PBGA package dimensions and thermal requirements. Confirm that the application circuit supports the required analog and digital supply voltages as specified in the datasheet.

Selection Notes

Select this component when a high channel count non-blocking switch matrix is required for professional video signals. Consider the 500 MHz bandwidth and low crosstalk specifications for high-fidelity signal routing. Evaluate the power supply flexibility and programming interface options to match system control architecture constraints.

Part Context

The AD8175 is part of Analog Devices' portfolio of high-speed video processing components. It is specifically engineered to handle demanding video switching tasks in professional environments. The device integrates a large switch matrix with independent output buffers, facilitating complex signal routing architectures without significant signal degradation.

Replacement Considerations

Consult the official Analog Devices replacement guide for verified substitute part numbers. Do not assume functional equivalence with other video switches based solely on pin compatibility.
