Broadcom has today released the BCM3472, the industry's first fully integrated 40nm Dual ISDB-T receiver chipset. Addressing the growing popularity of digital TV in Latin America, Broadcom is driving the deployment of digital terrestrial TV services in Brazil and a range of emerging markets around the world.

The new chip can be combined with Broadcom set-top box SoCs to launch Hybrid TV — digital terrestrial broadcast combined with advanced pay TV services. This enables operators to offer subscribers linear TV while adding new, advanced services like Digital Video Recorder and Video on Demand. By supporting Dual ISDB-T Receivers, Broadcom's solution is ideal for Hybrid STB and DVR solutions where multiple tuners must be included in the platform. The BCM3472's 12mm x 12mm package enables device manufacturers to save space and cost over existing solutions.

Additional Product Features:

-Integrates two receivers that include low-noise amplifiers with a tuner and demodulator on a single-chip that enables better cost and design efficiencies.

-RF loop through, daisy chain and clock sharing that eliminates the need for multiple crystals in a multi-tuner design.

-Broadcom's BCM3471 40nm Single ISDB-T device features an LNA, tuner and demodulator on a single-chip.

Sam Rosen, Senior Analyst, ABI Research:

Latin American countries are currently in the early implementation of their transition to digital terrestrial platforms, with Brazil leading the region. With this transition, we expect DTT households using the ISDB-T standard in Latin America to grow 400% between 2012 and 2017, to 17.5 million households. Many operators will launch Hybrid TV services, which leverage DTT for live, linear broadcasts while using satellite or IP networks to deliver advanced services, including VoD.

Dan Marotta, Broadcom's Executive Vice President and General Manager, Broadband Communications Group:

The BCM3472 supports the huge growth in pay TV households projected in Latin America in the next several years. Broadcom's ability to reach new levels of integration with the BCM3472 enables our customers to save space and cost, supporting the transition to Hybrid TV services. Now operators can cost-effectively deploy Hybrid TV solutions supporting pay TV and other services while also supporting existing digital terrestrial broadcasts.

Broadcom's BCM3472 and BCM3471 chips are currently sampling and will be shipping in mass production at the end of Q1 2013.
