AD8120ACPZ-R7

Overview

The AD8120ACPZ-R7 is a triple skew-compensating video delay line designed to correct time mismatches in unshielded twisted pair cables. It provides up to 50 ns of adjustable delay per channel with 0.8 ns resolution across 64 digital steps. The device features a fixed gain of 2, operates on ±4.5 V to ±5.5 V supplies, and supports SPI, I2C, or analog control. It offers a bandwidth of 200 MHz at zero delay and 150 MHz at maximum delay, housed in a 32-lead LFCSP package.

Feature Summary

• Corrects for unshielded twisted pair cable skew
• Independent red, green, and blue delay controls
• Digital and analog delay control options
• Drives four double-terminated video loads

Applications

• Keyboard-video-mouse (KVM)
• RGB video over UTP cable
• Professional video projection and distribution
• HD video
• Security video

Procurement Notes

Verify the specific suffix R7 indicates reel packaging when sourcing. Confirm the manufacturer is Analog Devices Inc. Ensure the component matches the 32-lead LFCSP physical form factor. Check datasheet specifications for operating temperature range and supply voltage requirements before integration.

Selection Notes

Select this component for applications requiring precise skew compensation between RGB video channels transmitted over twisted pair media. It is suitable where independent channel delay adjustment via digital or analog interfaces is necessary. Consider thermal dissipation capabilities and power supply stability for optimal performance.

Part Context
