MAX2170ETL+

Overview

The MAX2170ETL+ is a direct-conversion to low-IF tuner designed for satellite set-top and Very Small Aperture Terminal (VSAT) applications. It integrates a Sigma-Delta fractional-N synthesizer and operates within frequency ranges of 87 MHz to 108 MHz, 168 MHz to 240 MHz, and 1.452 GHz to 1.492 GHz. The device functions with a supply voltage between 2.7 V and 3.5 V. It is housed in a TQFN-EP-40 package.

Feature Summary

• Integrates a Sigma-Delta fractional-N synthesizer for precise frequency generation.
• Supports direct-conversion and low-IF receiver architectures.
• Designed specifically for satellite communication subsystems.

Applications

• Satellite set-top boxes
• Very Small Aperture Terminal (VSAT) systems
• Direct Broadcast Satellite (DAB) receivers

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm the specific revision level matches design requirements. Check current availability status as supply may be limited. Ensure proper handling procedures are followed during installation to prevent electrostatic discharge damage to the sensitive RF circuitry.

Selection Notes

Select this component when designing tuners for satellite reception requiring integrated synthesis. Consider the TQFN-EP-40 package constraints for PCB layout. Evaluate thermal management needs due to the integrated power amplifier stages. Verify that the operating voltage range aligns with the system power supply architecture.

Part Context

This part belongs to the Maxim Integrated RF tuner family, optimized for broadcast and satellite signals. It replaces older discrete tuning solutions by integrating multiple RF blocks into a single chip. The MAX2170 series provides a compact alternative to multi-chip modules for consumer electronics manufacturers.

Replacement Considerations

Check for MAX2170 variants with different suffixes for package or temperature grade changes. Verify compatibility with existing evaluation boards like the MAX2170EVKIT+. Consult official substitution guides for pin-compatible alternatives if the primary part is obsolete.
