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

Front Panel

• Bi-colour status LEDs, one for each DSP, one for each CPU, two for application status
• PLL lock status LED
• 4x SMP Rx, 4x SMP Tx RF connectors
• GPS antenna RF connector (SMP)
• Control connector to external power amplifier

Environmental Conditions

• Temperature (operating): 0ºC to +60ºC with forced air cooling
• Temperature (storage): -40ºC to +85ºC
• Relative Humidity: 10% to 90% at +55ºC (non-condensing)

• 45W typical (TBD)

Standard Compliance

• AMC.0 R2.0, AMC.2, IMPI V1.5 & V2.0, HPM.1
• CE, RoHS
• EN61000, EN5022, EN55024

Software

DSPs:

• Octasic FlexiPHY Firmware
• Four Software Defined Radio (SDR) PHY products
  • GSM, GPRS, EDGE PHY
  • UMTS/WCDMA/HSPA
  • LTE-FDD/LTE-TDD
  • CDMA 2000
• Up to 64 3G users
• Up to 130 / 50 Mbps LTE throughput
• Up to 20 Km range for all cellular standards
• Radio Utility System (RUS)

CPUs:

• Linux operating system

• Existing adaptation of Quortus core network software

System Integration

The NAMC-ODSP-W can be deployed in a variety of vRAN and C-RAN operating environments, including N.A.T.’s own range of MicroTCA systems. This enables developers to start with minimal capital expenditure, while providing a fully deployable platform.

Application Optimization

N.A.T. can adapt the NAMC-ODSP-W to suit your application-specific needs with for example, fewer DSPs or a larger FPGA. Please contact us to discuss your requirements.
