PXB4110ELV1.2-G

Overview

The PXB4110ELV1.2-G is a broadband analog front-end (AFE) integrated circuit designed for VDSL2 and ADSL2+ applications. It integrates a high-performance digital-to-analog converter (DAC), an analog-to-digital converter (ADC), and a programmable gain amplifier (PGA). The device supports full-duplex operation over single-pair copper lines, providing the necessary signal conditioning for vectoring-enabled systems. Key electrical parameters include a supply voltage range of 3.3V and operating temperatures from -40°C to +85°C. It features low power consumption modes and supports multiple line coding schemes required by ITU-T G.993.2 standards.

Feature Summary

• Integrated analog front-end with DAC, ADC, and PGA for VDSL2/ADSL2+ transceivers
• Supports vectoring and advanced noise cancellation techniques
• Low power consumption with configurable sleep and standby modes
• Digital interface compatible with standard DSL modem processors

Applications

• VDSL2 vectoring modems and gateways
• ADSL2+ network termination units
• Fiber-to-the-cabinet (FTTC) bridge devices
• Multi-service access points requiring high-speed broadband

Procurement Notes

Verify the specific revision suffix ELV1.2 against the manufacturer's latest datasheet to ensure compatibility with current design requirements. Confirm RoHS compliance status and check for any recent product lifecycle notices such as last-time buys or obsolescence warnings before finalizing procurement plans.

Selection Notes

Select this component when designing systems requiring integrated AFE functionality for VDSL2 vectoring applications. Ensure the host processor supports the required SPI or parallel interface protocols. Verify that the PCB layout can accommodate the thermal requirements and that the power supply rails meet the specified voltage tolerances for stable operation.

Part Context

This part belongs to Lantiq's (now Intel) portfolio of broadband communication solutions. It is typically paired with a DSL baseband processor to form a complete transceiver solution. The integration of the AFE reduces bill-of-materials count and simplifies board design compared to discrete solutions.

Replacement Considerations

Check for direct pin-compatible replacements within the same Lantiq family, such as other PXB4110 variants with different package options or temperature grades. Cross-reference with newer generations of AFEs if available, ensuring support for the same line codes and vectoring capabilities.
