XTRX Testing on ARM

A few people asked us about ARM support and most of them were interested in NVidia Tegra, so we grabbed a NVidia Jetson TK1 development kit for testing. Simple cross-compilation of the driver gives us 22 MSPS right away:

root@tegra-ubuntu:~/PKG/usr/lib# uname  -a
Linux tegra-ubuntu 3.10.40-ga7da876 #1 SMP PREEMPT Tue Jun 7 21:05:06 PDT 2016 armv7l 
armv7l armv7l GNU/Linux

root@tegra-ubuntu:~/PKG/usr/lib# ./test_xtrxll
Success!
Processed RX 2 x 11.000 = 22.000 MSPS (WIRE: 87.999299) TX 2 x 11.007 = 22.015 MSPS
(WIRE: 88.058852 MB/s) 
11:38:47.956458 INFO: XTRX PCI_4: Device closing

Not a bad result for an (almost) zero effort. We’ll see if we can optimize and get more performance out of it later on.

Stay tuned!

$599

XTRX Pro

Get an XTRX Pro board. Does not include any cables, antennas, or adapter boards.


$85

PCIe x2 Lite Adapter

This PCIe card securely holds an XTRX board (not included) so it can be used in a standard PCIe x4 slot. This adapter achieves the full 10 Gbit/s raw bus bandwidth and can be plugged into x4/x8/x16 PCIe slots. A six-pin JTAG connector makes it easy to program and debug the FPGA. Includes six SMA-to-U.FL cables, two screws for mounting your an XTRX board, and four 8 cm U.FL-to-U.FL cables.


$12

4G/LTE External Antenna

From the Crowd Supply Basics project.

Abracon External Antennas exhibit low return loss characteristics, high gain, and Low Voltage Standing Ratio (VSWR). These external antennas are linearly polarized and come in a low profile package.


$8

U.FL-to-SMA Cable

From the Crowd Supply Basics project.

A Hirose U.FL to SMA (jack) bulkhead straight connector with a 1.32 mm diameter cable. Less than -2 dB cable insertion loss up to 6 GHz. Both connectors are gold-plated brass and the cable conductor is silver-coated copper.


$11

Active GPS Antenna

From the Crowd Supply Basics project.

A low-noise active GPS antenna suited for the GPS L1 band. Accepts 3-5V DC and outputs RF via an SMA(m) connector. Optional adhesive mounting.
