PEF7072HLV16

Overview

The MaxLinear PEF7072HLV16 is a high-performance, low-voltage, 7-channel programmable filter designed for software-defined radio (SDR) and direct conversion receiver architectures. This device integrates seven independent continuous-time active filters within a single package, offering flexible frequency response shaping capabilities. It supports operation with supply voltages as low as 1.8V, making it suitable for portable and battery-powered applications. The filter characteristics are digitally programmable via an SPI interface, allowing dynamic adjustment of cutoff frequencies and gain settings to meet varying system requirements without external component changes.

Feature Summary

• Integrates seven independent continuous-time active filters in a compact package
• Supports low-voltage operation down to 1.8V for power-efficient designs
• Enables digital programming of filter parameters via SPI interface
• Optimized for direct conversion receiver and SDR applications

Applications

• Software-defined radio (SDR) front-end processing
• Direct conversion receiver architectures
• Portable communication devices requiring low power consumption
• Multi-standard wireless receivers needing flexible filtering

Procurement Notes

Verify the specific suffix LV16 indicates the correct voltage range and packaging variant against official MaxLinear documentation. Confirm that the SPI interface compatibility matches your system controller before procurement. Ensure thermal management solutions align with the device's power dissipation specifications under maximum operating conditions.

Selection Notes

Select this component when multiple independent filter channels are required in a space-constrained design. Consider its low-voltage capability if operating from a single 1.8V or 3.3V supply. Evaluate the need for digital programmability versus fixed analog filters based on system flexibility requirements. Verify that the available bandwidth and linearity specifications meet the target application's signal integrity needs.

Part Context

This part belongs to MaxLinear's family of programmable filter solutions aimed at simplifying RF front-end design. It replaces discrete filter networks with a single integrated solution, reducing board space and component count. The PEF7072 series is distinct from other MaxLinear products by focusing specifically on multi-channel continuous-time filtering rather than ADC or DAC functions.

Replacement Considerations

Check for updated revisions from MaxLinear that may offer improved performance or availability. Compare pin-to-pin compatible alternatives only if they maintain identical electrical characteristics and package dimensions. Verify that any substitute supports the same SPI command set to ensure seamless integration without firmware modifications.
