NAMC-ODSP-W

NAMC-ODSP-W: small cell and wireless processing for LTE, LTE-A, 5G and MIMO as single mid-size AMC module

Complete RF to L3 BTS functionality based on Octasic 2224W DSPs, Analog Devices AD9361 RF and NXP QorIQ LS1043A quad-core ARM processors


The NAMC-ODSP-W is aimed at LTE, LTE Advanced and 5G systems that require MIMO technologies and enables complete RF to Layer 3 wireless basestation functionality to be implemented on a compact, single-wide AdvancedMC module.

Combining four RF channels with DSP, FPGA and ARM based processing, this module includes a comprehensive range of software including a Linux operating system, L2/L3 stack, virtualized core network software and software defined radio PHY firmware.

A GPS antenna input on the front panel connects to GPS receiver circuitry for GPS clock synchronization. The front panel also features a control connector for an external power amplifier.

A variant of the NAMC-ODSP-W offers a dual SFP connector to the front panel to enable a CPRI link to external RF, allowing the module to be used in conjunction with third party remote radio head (RRH) solutions.

The standard variant of the NAMC-ODSP-W, with dual AD9361 RF-SoC devices, two channels of any cellular standard can run independently of each other. In the NAMC-ODSP-W variant with dual SFP connectors, each DSP will function independently, therefore the NAMC-ODSP-W can run up to two separate cellular channels of any cellular standard and use CPRI links to communicate with remote radio modules such as the N.A.T. NAMC-SDR.

Software

The NAMC-ODSP-W can run a variety of cellular software provided by Octasic and its trusted software partners. Octasic has developed physical layer (PHY) or Layer 1 software on the Octasic OCT2224 DSP for multiple cellular standards including GSM/GPRS/EDGE, CDMA2000, UMTS/HSPA, LTE-FDD/TDD and radio utility system (RUS). RUS is specialized software that provides network listen and RF player/recorder functionality on all cellular standards. RUS also includes a base station automatic synchronization system (BASS) module, which can be used to synchronize the internal clock of the NAMC-ODSP-W to commercial base stations in areas that GPS and external clock sources are not available.

Trusted partners of Octasic and N.A.T. offer higher layer protocol stack (Layer 2/3) and core network software for GSM/GPRS/EDGE, CDMA2000, UMTS/HSPA and LTE-FDD/TDD. All protocol stacks and core network software can run on the NXP ARM processor on the NAMC-ODSP-W or on external x86 or ARM CPUs. All software layers (L1/2/3 and core) are fully integrated and can be delivered as a turn-key solution. The integrated solution can be used in various scenarios such as private networks, wireless surveillance and research and development.

Applications

  • LTE
  • LTE Advanced
  • 5G Network Testing
  • MIMO and Massive MIMO

The NAMC-ODSP-W from N.A.T. combines a powerful FPGA with an array of DSPs, two quad-core ARM processors, four RF interfaces and advanced wireless software in a single-width, mid-size AMC module package.

RF Interface

  • Two Analog Devices AD9361 RF-SoCs offer four Rx and Tx antennas operating between 70Mhz and 6Ghz with up to 56Mhz analog bandwidth.The RF interface is implemented on a mezzanine module, so it can be easily adapted to new technologies or different RF front ends.

Alternative RF Interface

  • Dual SFP connector on front panel for CPRI links to external RF.
  • Backplane ports #2/3 usable for CPRI link to remote radio head (RRH)
  • Backplane ports #4-7 used for RF data exchange via 10G Ethernet 

 Subsystem Processor

  • Xilinx Kintex-7 XC7K160T (160k LE, 12Mbit internal SRAM, 8SerDes, 400 I/0)
  • Provides pre-DSP data manipulation while also giving you headroom for further extension and customization. This
    includes efficient linearization, i.e. using a single digital pre-distortion (DPD) per user insead of each power amplifier, and other data pre-processing capabilities.

PHY Processing Array

  • Four Octasic OCT2224W DSPs, each with twenty-four DSP cores, provide the specialized power needed for PHY processing.
  • Each DSP connects to two 16-bit wide DDR3 memory slots. Using 2Gb devices this results in 512MB DRAM per DSP.
  • Each DSP has two serial GbE connections to on-board Ethernet switch.
  • 3W typical power consumption.

L2/L3 and Core Processing

  • Two NXP QorIQ® LS1043A processors for L2/L3 and core processing.
  • Quad-core 64-bit ARM-based processors
  • Each supported by 4GB DDR4 memory
  • Data path acceleration
  • 5W typical power consumption

Switching

  • A Broadcom BCM5396 device establishes a full-non-blocking interconnect between the DSPs, CPUs, FPGA and backplane and provides an individual data and control path access to these devices.

Clock Interfaces

  • The NAMC-ODSP-W features a GPS antenna input connected to GPS receiver circuitry as well as an additional external reference clock input on the front panel, a TCLKA-D interface (receive or transmit) at the backplane connector , and an on-board Stratum-3 high precision oscillator.

Backplane Connectivity

  • Full AMC TCLKA-D connectivity
  • XAUI 10GbE (or custom SerDes protocol) connectivity to Fat-Pipe-Region ports #4-7
  • Dual 1GbE connectivity to ports #0 and #1
  • CPRI or custom SerDes protocol to ports #2 and #3
