MaxLinear ISDB-T Receiver Earns Industry Leading Brazilian LTE Immunity Certification

MaxLinear Inc. (NYSE: MXL), a leading provider of integrated radio frequency (RF) and mixed-signal integrated circuits for broadband communications applications, said today that its MxL683 has passed the new Brazilian LTE (News - Alert) immunity certification test conducted by Mackenzie Presbyterian University's DTV Laboratory in Sao Paulo, Brazil.

LTE interference with television reception is a significant issue for ISDB-T broadcasting markets. In Brazil, the LTE uplink band (starting at 703MHz) is located right next to the ISDB-T frequency band (ending at 698MHz) with peak transmit power from mobile phone at +23dBm. Under certain circumstances, the proximity of a strong LTE signal can severely affect the ISDB-T signal reception.

Government telecommunications authorities are looking carefully at this situation and mandating that TV and set-top box manufacturers increase the LTE interference protection in these systems. In Brazil, LTE immunity will be a key factor in the government's selection of a receiver that will qualify for a set-top box subsidy program.

MaxLinear's MxL683 ISDB-T receiver was architected to shield STB reception from worst-case LTE interference. The receiver is designed with robust front-end linearity to handle high-power LTE interferers.

Its unique system architecture provides excellent rejection to the close-in uplink LTE blockers. The demodulator design and smart automatic gain control (AGC) circuitry can very effectively handle the bursty nature of LTE signals.

In addition to passing LTE certification by Mackenzie University, the MxL683 has also been certified by the Brazilian telecommunications regulatory authority where the device was the only front-end receiver to pass all tests without the need for a bulky and costly mechanical LTE filter.

"The LTE interference challenge to ISDB-T broadcast systems is just now being felt as LTE networks strt to expand in Brazil and many other countries. Governments are recognizing this challenge and acting to protect the integrity of their broadcast networks," said Yves Rasse, Senior Product Line Director for Satellite and Terrestrial TV. "In the lab and in the field, the MxL683 continues to impress customers with its unmatched LTE interference immunity and its best-in-class reception performance."

Technical Highlights

Thanks to its RF systems and OFDM demodulator performance, the MxL683 achieves best-in-class performance, including sensitivity, LTE immunity and multi-path fading performance. The unmatched adjacent and co-channel interferer immunity provides assurance that set-top boxes will be reliable and robust in a crowded TV spectrum.

The MxL683 is fully compliant with the Japanese ISDB-T (ARIB STD-B21) and Brazilian SBTVD-T (ABNT NBR 15604) terrestrial TV receiver specifications. Additional features include auxiliary channel decoding for emergency broadcast warning system, high accuracy receiver signal strength indicator (RSSI), and fast channel scan algorithm to reduce the set-top box scan time by up to 50 percent.
