AD8124ACPZ-RL

Overview

The AD8124ACPZ-RL is a triple, high-speed differential receiver and equalizer designed to compensate for transmission losses in UTP and coaxial cables up to 200 meters. It operates on a single supply voltage ranging from 4.5 V to 5.5 V with a quiescent current of 132 mA. The device features adjustable frequency response controls including VPEAK, VGAIN, and VPOLE, alongside an output offset adjustment pin (VOFFSET). It provides fast rise and fall times of 8 ns at 200 meters and includes two internal comparators for sync extraction.

Feature Summary

• Triple-channel architecture compensates for cable transmission losses up to 200 meters using adjustable gain stages.
• Includes three control pins for optimizing frequency response across different cable types and lengths.
• Integrates two on-chip comparators with hysteresis for common-mode sync pulse extraction.
• Features low output offset voltage and DC output offset adjustment for flexible system integration.

Applications

• Keyboard-video-mouse (KVM) systems
• Digital signage displays
• RGB video transmission over UTP cables
• Professional video projection and distribution
• HD video and security video applications

Procurement Notes

Verify the specific ordering suffix RL indicates reel packaging when sourcing components. Confirm that the LFCSP-40 package matches your PCB footprint requirements. Ensure power supply filtering meets the ±5 V specification for optimal performance. Check for moisture sensitivity handling instructions during assembly. Validate that the operating temperature range covers your intended environment.

Selection Notes

Select this component for applications requiring long-distance video signal restoration over twisted pair or coaxial media. The adjustable pole and peak controls allow optimization for varying cable gauges and types. Consider the integrated comparators if sync extraction is needed without external logic. Evaluate thermal dissipation capabilities given the 40-lead LFCSP package constraints.

Part Context

This part belongs to the AD8124 series of triple differential receivers. It serves as a complementary receiver to drivers like the AD8134 and AD8148 which encode sync pulses. The device is rated for operation between −40°C and +85°C. It utilizes a 6 mm × 6 mm LFCSP package for compact board space utilization.

Replacement Considerations

Check for AD8124ACPZ-R7 for tape-and-reel alternatives. Verify AD8124ACPZ for tray-packaged equivalents. Review AD8123ACPZ-RL for similar triple equalizer functions with different bandwidth characteristics.
