Update & 33C3 Talk: Lessons learnt in building a low latency, high throughput PCIe based SDR

Talk

We recently gave a talk and a workshop at 33rd Chaos Communication Congress aka 33C3 on funny and not so funny issues one faces while building a high performance SDR. If you missed 33C33, video recording of the presentation is available here (and slides are attached here).

When we prepared the talk, we listed all challenges Sergey had while debugging PCIe, but the list went so long that we had to move it to a separate workshop. So this talk was focused on more generic issues without going deep into PCIe internals, which I hope will be interesting for a wider audience working on SDR devices and aiming to achieve maximum performance.

Update

We know the blog has been silent for a while, but the talk shows some of the challenges we have been facing in getting the most out of XTRX. And the significant effort that is being put into making a solid product which “just works” – as far as it’s possible with SDR of course. :-).

At this moment we’re very close to place an order for the next prototyping run which (if no new critical bugs shows up) will be available for selected early adopters.

Stay tuned!

Product Choices

$260

XTRX

Get an XTRX revision 4 board. Does not include any cables, antennas, or adapter boards.


$515

XTRX Deluxe Bundle

Get an XTRX revision 4 board as well as an Antennas + Cables set, a PCIe x2 + Front End Adapter, and a USB 3 Adapter with Aluminum Enclosure (see below for details). Also comes with four extra U.FL-to-U.FL cables and four extra U.FL-to-SMA-male cables.


$59

Antennas + Cables

A full complement of cables and antennas for your XTRX, including four RF antennas (95 mm, 2 dBi, SMA male, GSM/3G/LTE 880 - 960 MHz, 1710 - 1990 MHz), one GPS antenna, and five cables.


$79

USB 3 Adapter with Aluminum Enclosure

This adapter converts your XTRX from Mini PCIe to USB 3 and comes with an aluminum enclosure designed specifically for XTRX. The adapter has three status LEDs, a micro USB 3 port, one SMA connector for the GPS antenna, four SMA connectors for the MIMO Tx/Rx antenna pairs, a micro SIM card slot, and a slot for a GPIO FPC cable. Comes with a USB cable and all RF cables for internally connecting an XTRX to the SMA connectors. Does not include an XTRX, antennas, or FPC cable.


$99

PCIe x2 + Front End Adapter

This PCIe card securely holds an XTRX board (not included) so it can be used in a standard PCIe x4 slot. It includes an RF front end with a LNA and PA for up to 100 mW output on each channel. A TDD switch is incorporated for applications like TDD LTE. You can bypass the front end by attaching cables directly to XTRX. 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. A micro SIM card slot is also present.


$2,900

XTRX PCIe Octopack

This single PCIe card comes loaded with eight (8!) removable XTRX boards, metal installation brackets, enough cables for all GPS and MIMO Tx/Rx ports, and a special board for synchronizing all eight XTRX boards.


$1,900

XTRX Beta Tester

Here's your chance to get an XTRX board as soon as possible. We'll send you an XTRX revision 3 board as soon as the campaign reaches its funding goal and we'll follow up with a production version (revision 4) as soon as they come off the assembly line.
