1 Ettus Research Products and Roadmap 2011 Matt Ettus Ettus Research September, 2011

2 Outline

3 Outline

4 Ettus Research founded in 2004 Acquired by National Instruments in Feb 2010 Now operating as a wholly-owned subsidiary Based in Mountain View, CA Currently 10 employees

5 Business Model Sell low-cost, easy to use software radio kits Build a community of users Keep a very low overhead Fit into the niche between consumer-level and test equipment level price and performance Engineering Model Use mid-sized, low-cost FPGAs Allow user to reprogram, build o of our open-source IP Leverage from, and give back to the Open Source community Rapid design turnaround, keep up with the latest chips and capabilities Use highly-integrated parts where possible Universal drivers allow use with any software stack

6 Outline

7 Goals Very low cost Interchangeable RF sections Wide bandwidth Extreme exibility MIMO-capability Create a community of user-developers Developed in parallel with GNU Radio Don't constrain what the user does

8 Architecture USRP Motherboard interfaces computer to analog Bus or network interface to host FPGA Dual high-speed ADCs and DACs for Quadrature signals Low speed ADCs and DACs for RSSI, gain ctrl, etc. Clock generation GPIOs, I2C, SPI Interchangeable daughterboards convert analog baseband to RF Quadrature Up/Downconverters VCO/PLL for LO LNA, PA, all ltering

9 Universal Hardware Driver (UHD)

10 UHD Works on Linux, Mac, Windows Using CMAKE for cross-platform build system Windows build with Visual Studio, Cygwin, MinGW LabVIEW, Simulink, GNU Radio, OpenBTS, and OSSIE all support UHD now Supports all of our hardware transparently Dual-license model (GPL + Other) Handles arbitrary MIMO congurations

11 FPGA Design Digital up- and downconverters CORDIC algorithm Decimation and Interpolation CIC and halfband lters Data formatting, packetizing, and bus interfacing Daughterboard Control Precise timing Room for user expansion

12 Outline

13 USRP1 Introduced in 2005 USB 2.0 Interface 8 MHz of RF bandwidth at 16 bits per sample Altera Cyclone I FPGA 64 MS/s 12-bit ADCs, 128 MS/s 14-bit DACs 2x2 MIMO capable $700

14 USRP1 Matt Ettus Ettus Research Products and Roadmap 2011

15 USRP2, N200-series Gigabit Ethernet interface 25 MHz of RF bandwidth at 16 bit samples Xilinx Spartan FPGA (USRP2) Xilinx Spartan 3A DSP 1800A (N200) or 3400A (N210) 100 MS/s 14-bit ADCs, 400 MS/s 16-bit DACs External 10 MHz reference and PPS input MIMO Expansion Support for in-box GPSDO $1400-$1700

16 USRP N210

17 USRP E100-series Embedded computer built-in OMAP MHz ARM Cortex A8 with oating point SIMD extensions 520 MHz TI C64x xed-point DSP Spartan 3A DSP (-1800 on E100, on E110) High-speed bus between FPGA and OMAP Audio In/Out, HDMI video 10/100 Ethernet USB Host, USB On The Go, USB console

22 USRP Embedded Highlights Runs REAL Linux No need to choose between GPP, DSP, or FPGA processing Can develop directly on E100/E110 Develop on desktop with USRP1/2/N210, deploy (same code!) on Embedded Uses UHD Low power, no laptop Low latency with direct bus access

23 Embedded Usage Model Network testbeds Wireless sensor nodes Public safety nodes Picocells Low-cost SIGINT boxes

24 Daughterboards BasicRX and BasicTX Transformer-coupled breakout board LFRX and LFTX Dual DC-30 MHz TVRX2 Dual 50 MHz to 860 MHz receive-only DBSRX2 800 MHz to 2.4 GHz receive-only RFX (all full duplex, mw output power) RFX MHz RFX MHz RFX MHz RFX MHz XCVR GHz, GHz WBX 50 MHz to 2.2 GHz, Full duplex SBX 400 MHz to 4.4 GHz, Full duplex
