The Sundance Series NMI320 is a System-on-Chip (SoC) Integrated Circuit (IC) that implements the Integrated Services Digital Broadcasting for Terrestrial Television Broadcasting (ISDB-T) specifications of the Association of Radio Industries and Businesses (ARIB) Standard STD-B29. Specifically, the NMI320 supports 1- and 3-segment ISDB-T reception. Figure 1 shows that the NMI320 is an SoC that implements the RF tuner, demodulator, decoder/deinterleaver, and peripherals on a single die.
 
 
 
The key features of the NMI320 are:

• Fully compliant 1-segment and 3-segment ISDB-T reception according to ARIB Standard STD-B29
• Power consumption: Less than 75 mW in 1-seg mode and 90 mW in 3-seg mode
• Built-in ultra low power CMOS RF tuner
• Fully integrated VCOs, PLL loop filter and crystal oscillator
• Ultra-low sensitivity: -98.8 dBm for QPSK mode rate ½ in UHF/VHF band (13-segment power)
• Superior linearity: Up to +13dBm maximum input signal
• Fully integrated wideband LNAs and matching networks
• Integrated 11-bit ADC for IF signal
• ACI and CCI (adjacent & co-channel interference) digital filtering
• Dual AGC control of RF and IF gain
• Automatic mode and guard detection
• Automatic symbol synchronization and tracking
• Automatic digital carrier recovery over wide range of offsets (no ext AFC required)
• Automatic digital timing recovery (no external VCXO required)
• Common phase error correction
• TMCC (Transmission and Multiplexing Configuration Control) decoding and error checking
• Automatic frame sync
• On-chip Time-domain Deinterleaving for both 1-segment and 3-segment mode with no external RAM
• requirements
• Configurable serial/parallel transport stream interface
• Flexible host interface via SDIO, SPI, I2C, and EBI interfaces
• Includes device drivers and middleware support all popular processors and operating systems
