Overview
The AD8123ACPZ-R7 is a triple differential receiver with adjustable line equalization designed to compensate for transmission losses in UTP and coaxial cables up to 300 meters. It features a 55 dB peak gain at 100 MHz, a 120 MHz -3 dB large signal bandwidth, and operates on ±4.5 V to ±5.5 V supplies with 132 mA quiescent current per supply rail.
Feature Summary
- Triple-channel architecture compensates for cable losses up to 300 meters
- Adjustable high-frequency peaking and broadband flat gain via control pins
- Integrated comparators for common-mode sync pulse extraction
- Low output offset voltage of 24 mV with DC offset adjustment capability
Applications
- Keyboard-video-mouse (KVM) systems
- RGB video distribution over UTP cables
- Professional video projection and distribution
- HD video and security video applications
Procurement Notes
Verify the specific suffix R7 indicates reel packaging when sourcing. Confirm the manufacturer is Analog Devices Inc. Ensure the component meets RoHS requirements as specified in official documentation. Check for moisture sensitivity level constraints during storage and handling.
Selection Notes
Select this device for applications requiring compensation of long-distance UTP or coaxial cable transmission losses. The adjustable control pins allow optimization for different cable types and lengths. Ensure the system supports dual power supplies within the ±4.5 V to ±5.5 V range.
Part Context
This component belongs to the AD8123 series of triple differential receivers. It is part of Analog Devices' portfolio of video amplifiers and equalizers designed for high-speed signal integrity restoration in professional video and data transmission environments.
Replacement Considerations
Public confirmed substitutes include other triple differential receivers from Analog Devices such as the AD8143 or AD8145 for higher CMRR requirements. Verify pin compatibility and electrical specifications before substitution.
FAQ
How does the AD8123 handle sync pulse extraction?
It includes two on-chip comparators with hysteresis that can extract horizontal and vertical sync pulses encoded in the common-mode voltages of RGB signals.
What is the maximum cable length supported?
The AD8123 is designed to compensate for transmission losses in UTP and coaxial cables up to 300 meters in length.
Can the AD8123 be used with coaxial cable?
Yes, by adjusting the VPOLE control pin according to recommended settings for coaxial cable, it can effectively compensate for losses in 75 Ω video cable.
