AD8142ACPZ-R2

Overview

The AD8142ACPZ-R2 is a triple, low-cost differential driver manufactured by Analog Devices Inc. It operates on a single 5 V or split supply and features a fixed gain of 2 to compensate for line termination attenuation. The device includes an integrated sync-on-common-mode circuitry for transmitting balanced horizontal and vertical video sync signals over common-mode channels. It utilizes a 24-lead 4 mm × 4 mm LFCSP package and supports operation from −40°C to +85°C.

Feature Summary

• Triple high-speed differential drivers optimized for wideband video applications
• Integrated sync-on-common-mode circuitry for embedding HSYNC and VSYNC signals
• Internal common-mode feedback network ensuring output amplitude and phase matching
• Disable feature providing high-Z outputs for line isolation and multiplexing

Applications

• Keyboard-video-mouse (KVM) networking
• Video distribution systems
• Digital signage
• Security cameras

Procurement Notes

Verify the specific ordering suffix R2 against the manufacturer's official documentation to confirm reel packaging specifications. Ensure compatibility with the required PCB footprint for the 24-lead LFCSP package. Confirm that the voltage supply range aligns with system requirements before integration.

Selection Notes

Select this component when RGB signal transmission requires embedded synchronization signals on the common-mode lines. The internal common-mode feedback ensures high balance error performance without external adjustments. Consider the AD8141 if sync-on-common-mode functionality is not required for the specific application design.

Part Context

This part belongs to the AD8141/AD8142 family of low-cost triple differential drivers designed for high-resolution video. While the AD8141 provides standard differential driving, the AD8142 variant specifically integrates circuitry to handle video synchronization signals within the common-mode voltage levels, facilitating simpler cable transmission architectures.

Replacement Considerations

Public confirmed substitute part numbers include AD8141ACPZ-R7 for standard differential driving without sync capabilities.
