Broadcom's 65-nm digital TV single-chip receivers support the DVB-T (Digital Video Broadcast-Terrestrial) and DVB-H (Digital Video Broadcast-Handheld) standards.
The BCM2940 integrates a dual-mode demodulator and tuner to support both DVB-T and DVB-H for the high-growth cellular handset market. The BCM2930 is optimized for DVB-T applications targeting set-top-box and PC markets, and enables digital TV broadcasts as a value-added feature on portable platforms.
An aggressive process technology implementation means the BCM2940 and BCM2930 significantly reduce power consumption by up to 40% and footprint requirements by up to 30% from current handset design budgets. Advanced tuner and demodulator design of both chips allows for measurably improved reception indoors and in high-speed environments.
The BCM2940 and BCM2930 receivers integrate state-of-the-art RF tuners with standards-compliant DVB-T and DVB-H digital basebands on single die. They support the VHF III, UHF IV and V bands. The BCM2940 additionally supports the EU/US L-bands and integrates 4Mb MPE-FEC SRAM to handle DVB-H parallel/consecutive streams and services.
Both offer a variety of physical interfaces including SPI, SDIO and USB 2.0. In addition, the receivers functionally:
- Exceed IEC 62002 (MBRAI) specifications for mobile video applications
- Improve signal reception: -98dBm sensitivity DVB-T mode (QEF, QPSK-1/2) for all UHF/VHF channels, <3 dB noise figure for all bands while exceeding MBRAI specifications
- Extend battery life: 160mW power consumption (typical conditions), 209mW with significant margin over MBRAI specifications (DVB-T mode). Very low between time-slice power of <0.8mW (DVB-H mode)
Both the BCM2940 and BCM2930 are available in an FBGA package and the BCM2940 is also available in a WLBGA package. Both mobile TV devices and firmware are now sampling to qualified customers. Pricing is available upon request.
