AVL6862TA

Overview

The Availink AVL6862TA is a single-chip demodulator supporting DVB-T2, T, C, S2, and S standards. It handles terrestrial/cable via Low IF or high IF (36 MHz) inputs and satellite via zero IF input. The device supports all DVB-T2 modes including SISO/MISO, FEFs, and Base/Lite profiles with bandwidths from 1.7 to 8.0 MHz. For DVB-C, it covers QAM modes up to 256QAM and symbol rates of 0.87 to 9 Msps. DVB-S/S2 support includes QPSK/8PSK symbol rates up to 55/45 Msps respectively. It features automatic standard detection, blind scanning, and firmware-upgradeable architecture in a 48-pin 6x6 mm QFN package.

Feature Summary

• Supports multi-standard demodulation for DVB-T2/T/C/S2/S with automatic acquisition and switching capabilities.
• Flexible input architecture accommodating Low IF/high IF for terrestrial/cable and zero IF for satellite signals.
• Comprehensive modulation support including advanced DVB-T2 modes like Future Extension Frames and multiple PLPs.
• Firmware-upgradeable design allowing performance enhancements without hardware changes.

Applications

• Digital television set-top boxes
• Cable modem termination systems
• Satellite receiver front-ends
• Broadcasting equipment

Procurement Notes

Verify the specific suffix 'TA' against the manufacturer's official documentation to confirm exact packaging, temperature range, or binning specifications. Ensure compatibility with existing system designs by checking pin-to-pin compliance with referenced Availink models such as the AVL6762 or AVL6812 if migration is required. Confirm interface voltage levels and MPEG output configurations prior to integration.

Selection Notes

Select this component for applications requiring a unified solution for terrestrial, cable, and satellite signal reception. Its firmware-upgradeable nature supports long-term product viability. Consider the 48-pin QFN package constraints for PCB layout. Verify that the target market standards align with the supported DTG and Nordig compliance levels for terrestrial variants.

Part Context

The AVL6862TA belongs to Availink's family of multi-standard demodulators. It shares pin compatibility with other chips in the series, such as the AVL6762, AVL6812, and AVL6882, facilitating design flexibility across different regional broadcasting standards. This integration reduces bill-of-materials complexity by consolidating multiple demodulation functions into a single silicon solution.

Replacement Considerations

Pin-to-pin compatible with Availink AVL6762, AVL6812, and AVL6882. Verify functional requirements against these alternatives to ensure sufficient standard coverage for the specific application.
