ADV3228ACPZ

Overview

The ADV3228ACPZ is an 8 × 8 high-speed analog crosspoint switch matrix manufactured by Analog Devices Inc. It operates on ±5 V supplies and features buffered inputs with programmable high-impedance outputs to prevent off-channel loading. The device provides a +1 voltage gain and supports serial or parallel programming for flexible control. It delivers a −3 dB large signal bandwidth of 750 MHz at 2 V p-p, a slew rate of 2500 V/µs, and low power consumption of 0.5 W. The component is housed in a 72-lead LFCSP package (10 mm × 10 mm) and functions within an extended industrial temperature range of −40°C to +85°C.

Feature Summary

• Nonblocking 8 × 8 switch array architecture
• Buffered inputs with programmable high-impedance outputs
• Serial or parallel digital control interface
• Drop-in compatible with AD8108/AD8109

Applications

• Routing of NTSC, PAL, S, SECAM, YUV, and RGB video signals
• Compressed video routing including MPEG and wavelet formats
• Telecommunications signal switching
• Data communications infrastructure

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure correct package type and temperature rating. Confirm that the supply chain source provides valid traceability and authenticity guarantees. Check for any recent product change notices regarding pinout or electrical specifications before finalizing procurement orders.

Selection Notes

Select this component when an 8 × 8 nonblocking analog matrix with a +1 gain configuration is required. Ensure the application environment accommodates the specified ±5 V dual supply rails. Verify that the system design can manage the thermal dissipation limits associated with the 72-lead LFCSP package under maximum operating conditions.

Part Context

This part belongs to the ADV3228/ADV3229 family of high-speed analog crosspoint switches. It serves as a functional equivalent to the legacy AD8108/AD8109 series, facilitating direct upgrades in existing designs. The device is designed to act as a building block for constructing larger multicast-capable crosspoint arrays through bus paralleling.

Replacement Considerations

The ADV3228ACPZ is functionally equivalent to the AD8108. Designers may consider the ADV3229ACPZ if a +2 gain output buffer is preferred instead of the +1 gain provided by the ADV3228.
