For 5G – URLLC, MMTC and IoT applications, Socionext has various IPs and chip solutions to support multiple applications driven by this technology. These include dedicated high quality, low power image signal processors, fully qualified digital and mixed-signal graphic (display) controllers or Codec ICs for professional AV equipment or compact solutions. Socionext offers for dedicated IoT communications, wireless LPWA (Low power Wide Area Low cost) chip sets or wired (power line) LSIs for very stable and secure data transmissions supporting home, building, maintenance, process or factory automation as well as smart grid and smart surveillance solutions.
For5G – EMBB with sub 6GHz Bands (5G Primary Band) using higher channel bandwidth, higher data rate and having contiguous spectrum availability, Socionext has IPs and ASIC solutions that are well qualified for. Digital Front End (DFE) or Active Antenna Unit (AAU) applications.
For DFE, a novel, dedicated direct RF architecture with multiband communication could be used. This requires fast, highly efficient A/D converter IPs with a sufficiently large bandwidth to digitize the given frequency band, and a DSP.
Compared to a traditional (heterodyne) solution, the direct RF solution does not require any mixers, amplifiers or filter blocks. This simplifies the system immensely by reducing the number of required components and power consumption, as shown in Figure 1. In addition, the integrated DSP allows for intelligent compensation and optimization techniques and enables flexible bandwidths in a digitally selectable frequency band, which could revolutionize mobile network expansion. A/D converter IPs could use, for example, optimized sampling rates ≥ 32 GSa /s, a resolution of ≥12 bit, and a -3dB BW of ≥7 GHz.
For AAU, a large number of A/D converters can be integrated into an ASIC with low power consumption and size, which is a requirement for the focusing (MIMO beamforming) of signals to mobile units and devices as shown in Figure 2. Massive MIMO antenna arrays with small dual-polarized path antennas would be driven by fully digital transceiver chains.
For 5G – EMBB (e.g. Small Cells) using mmWave Bands (known as 5G Complementary Bands) at high frequencies (>28GHz) but with small wavelength/bandwidth, a highly directive point-to-point beam, with spatial multiplexing, can be used. This allows for less interference and more efficient use of the transmit/receive power which is important due to the high link loss. Socionext offers A /D converter IPs with sampling rates ≥ 2GSa/s, a resolution ≥14Bit, and a -3dB-BW from DC to above 500MHz.
Other Wireless- u. Satellite applications using μWave, or terahertz (THz) transmission links, which are seen as supporting technologies for high-speed extensions of wireless communication networks, can also benefit from such low power and small sized IP portfolios.
