BCM3461

DVB-T/T2/C Receiver with Integrated Tuner

The BCM3461 is Broadcom's first fully integrated 40nm DVB-T2 receiver - driving the deployment of digital terrestrial services in at least 28 countries throughout the world that have formally adopted this standard. Broadcom's new monolithic device enables a significantly smaller and lower cost design.

The BCM3461 combines a DVB-T, DVB-T2, and DVB-C compliant demodulator with an LNA, 1 GHz SCTE40+ terrestrial tuner, all required memory, and a MIPS M4K-based acquisition processor.
