MAX5862AUXH+

Overview

The MAX5862AUXH+ is an integrated downstream cable QAM modulator, digital upconverter (DUC), and RF digital-to-analog converter. It supports eight-channel operation within a frequency range of 47MHz to 1.006GHz. The device utilizes a 280-FCBGA package measuring 12x17 mm. It combines high-density modulation with direct RF output capabilities for cable television infrastructure.

Feature Summary

• Integrates eight-channel downstream QAM modulation functionality
• Includes digital upconversion and RF digital-to-analog conversion stages
• Supports wideband frequency coverage from 47MHz to 1.006GHz

Applications

• Cable television headend systems
• Downstream signal generation for hybrid fiber-coaxial networks
• RF signal processing in broadband communication infrastructure

Procurement Notes

Verify the suffix 'U' indicates the specific temperature and package variant. Confirm the '+' suffix denotes compliance with RoHS standards. Ensure the 280-FCBGA footprint matches the target PCB design. Cross-reference the manufacturer's latest datasheet for pinout accuracy before integration into production hardware.

Selection Notes

Select this component when requiring multi-channel downstream modulation in a single integrated solution. It is suitable for applications needing direct RF output without external mixers. Consider the FCBGA package size constraints during board layout planning. Evaluate thermal performance requirements given the high integration density of the DUC and DAC functions.

Part Context

This part belongs to the MAX5862 family of integrated cable modulators. It represents a consolidation of multiple discrete RF and digital components into a single chip. The device simplifies system design by handling both digital upconversion and analog modulation tasks simultaneously for downstream transmission.

Replacement Considerations

Check Analog Devices documentation for updated revisions or alternative packages within the same functional family. Verify compatibility with existing firmware or control logic if substituting with similar channel-count devices.
