MAX2163AETL+

Overview

The MAX2163AETL+ is a direct-conversion to low-IF tuner designed for digital television (DTV) applications. It integrates a quadrature downconverter, programmable gain amplifier (PGA), and analog-to-digital converter (ADC). The device supports multiple DTV standards including ATSC, DVB-T/C, ISDB-T, and DTMB. It operates from a single 3.3V supply and features an integrated voltage-controlled oscillator (VCO) and loop filter components. The component is housed in a compact 40-terminal TQFN package measuring 5mm x 5mm with an exposed thermal pad.

Feature Summary

• Integrates quadrature downconversion, PGA, and ADC for simplified system design
• Supports multiple global digital television broadcast standards
• Includes integrated VCO and loop filter to reduce external component count
• Optimized for low power consumption in portable and embedded devices

Applications

• Digital TV tuners for set-top boxes
• Portable DTV receivers
• Embedded communication systems requiring RF downconversion
• Desktop DTV receivers

Procurement Notes

Verify the specific suffix (+ or -T) against the manufacturer's current datasheet to confirm RoHS compliance and tape-and-reel availability. Confirm that the 40-TQFN package dimensions match your PCB footprint requirements. Check for obsolescence status as Analog Devices frequently updates component lifecycles. Ensure the supplier provides valid traceability documentation for authorized distribution channels.

Selection Notes

Select this component when a highly integrated solution for DTV reception is required to minimize board space. Consider the single-supply operation and integrated reference if power management complexity needs reduction. Evaluate the supported frequency ranges against your regional broadcast standards. Verify thermal performance requirements due to the exposed pad package design for heat dissipation.

Part Context

This part belongs to the Maxim Integrated MAX21xx series of RF tuners, widely used in consumer electronics for digital television reception. The MAX2163 variant specifically targets low-IF architectures, offering a balance between performance and integration level compared to direct-conversion-only or super-heterodyne solutions. It represents a mature product line within Analog Devices' portfolio for broadcast applications.
