BCM2940 - DVB-H and DVB-T Single-Chip Tuner + Demodulator for Mobile Applications

DVB-H and DVB-T Single-Chip Tuner + Demodulator for Mobile Applications

The Broadcom BCM2940 is a monolithic 65-nm single-chip mobile digital TV receiver for both DVB-T and DVB-H standards. Combining a high-quality RF tuner with a complete DVB-T/H digital baseband on a single monolithic CMOS IC, the BCM2940 sets new standards for integration and mobile performance. The BCM2940 supports VHF III, UHF IV and UHF V bands, and both 1450 MHz - 1490 MHz and 1670 MHz - 1675 MHz L-bands. It is suitable for digital TV reception on portable devices almost anywhere in the world.

Broadcom's OptimRF™ technology is based on the optimal combination of state-of-the-art CMOS RF design and proprietary architectural and algorithmic innovations. OptimRF technology compensates for process and performance deviations, keeping device operation within target specifications. OptimRF improves manufacturing yield by avoiding costly trimming and optimizing power consumption.

  • Multiband VHF III (170 MHz - 240 MHz), UHF IV and V (470 MHz - 862 MHz) and L-band (1400 MHz - 1700 MHz) support with 3dB Noise Figure (NF) Tuner
  • Low 209mW in continuous operation with significant margin over MBRAI, Nordig Unified, Digitenne, and D-Book specifications; between time-slice power: < 0.8 mW in DVB-H mode
  • Standards compliance with DVB-H (ETSI EN 302 304), IEC-62002 (MBRAI), supports DVB-H parallel and/or consecutive streams and services, and Nordig Unified v1.0.3, Digitenne, and D-Book
  • Ideal for broadcast TV in mobile phones, Portable Navigation Devices (PNDs), and Portable Media Players (PMPs).
