AD8124ACPZ

Overview

The AD8124ACPZ 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 features adjustable frequency response gain pins (VPEAK, VGAIN) and pole location adjustment (VPOLE). The device operates on ±4.5 V to ±5.5 V supplies with quiescent currents of 132 mA and 126 mA. Key performance metrics include an 8 ns rise/fall time at 200 meters, 37 dB peak gain at 100 MHz, and a low output offset voltage of 24 mV. It integrates two comparators for sync extraction and is housed in a 40-lead LFCSP package.

Feature Summary

• Compensates cable transmission losses for lengths up to 200 meters using adjustable gain stages.
• Includes three control pins for optimizing frequency response and pole location across different cable types.
• Integrates two on-chip comparators with hysteresis for common-mode sync pulse extraction.
• Features high-impedance differential inputs suitable for direct interfacing with video cables.

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 suffix 'ACPZ' corresponds to the 40-lead LFCSP package variant when ordering. Confirm that the supply chain documentation matches the Analog Devices manufacturing origin. Ensure compatibility with the required ±5 V power supply rails and thermal management requirements for the exposed paddle connection.

Selection Notes

Select this component for applications requiring long-distance video signal restoration over twisted pair or coaxial media. The adjustable control pins allow optimization for specific cable gauges and types. Consider the integrated comparators if sync extraction is needed without external logic. Verify that the system can accommodate the dual ±5 V power supply requirement and the thermal dissipation limits of the LFCSP package.

Part Context

The AD8124 belongs to a family of triple differential receivers from Analog Devices. It serves as a complementary receiver to drivers like the AD8134 and AD8142. The ACPZ designation indicates the lead-free, RoHS-compliant version in the specified surface-mount package. It is distinct from RF amplifiers or data acquisition cards sharing similar numerical prefixes.
