Ozy - What is it?
The Ozy module is an FPGA based interface controller card that provides the input and output connections to the real world. An Altera Cyclone II FPGA provides numerous control lines for interfacing the various boards connected to the Atlas backplane. Ozy also provides a high speed USB 2.0 interface to the controlling PC. The USB interface uses a Cypress FX2 chip which has greatly simplified the design and development effort. The FX2 supports full duplex USB communications at a measured 35MB/s, which should allow sufficient bandwidth for current and future requirements. The Cyclone II FPGA also provides the necessary control logic and data formatting for the Janus board as well serial and parallel interfaces for user defined I/O. One highly desirable feature of the Ozy board is the ability to measure the various high frequency crystal oscillators used by the HPSDR by using the 1 pps clock from a GPS receiver. The GPS clock can be used to gate the various oscillators and report the count to the PC via the USB interface. Since the PC will have prior knowledge of exactly what these frequencies should be, any errors can be corrected in software. The result will be a radio with extremely high frequency accuracy and stability -- a boon for microwave operators. In conjunction with Janus, Atlas and a suitable power supply it becomes a part of a Software Defined Radio (SDR) system which performs A/D and D/A conversions as well as control functions.
For the hobbyist, student and even professional, the Ozy represents a very competitively priced way of learning and experimenting with FPGA development. An added bonus is that all the software to develop code is either available under the GPL or via free download. Apart from use with an SDR there are numerous other areas where an FPGA development board can be used.
Ozy is an experimental device and may not be suitable for your application.
Ozy - What it is not!
Ozy is not an SDR. It does not function as a stand alone card. It currently requires the Atlas backplane and power supply to provide a minimally functional system.
Ozy - Why?
Many modern PCs (especially laptops) do not have parallel ports necessary to control an SDR. Ozy allows parallel I/O under control of a standard PC USB port. In conjunction with Janus, even digitized receive and transmit data can be sent and received by the PC. This allows the USB port to function as a complete SDR interface to the PC.
When will Ozy be delivered?
A&T units are sold out and will no longer be available from TAPR. Bare PCB are still available, see below.
OZY IS SOLD ON AN AS-IS BASIS WITHOUT WARRANTY OF ANY KIND.
All Ozy boards will be tested prior to shipment, and all boards will be working when they are shipped. To the extent that we have available inventory, we may, at our discretion, agree to a one time only exchange. This is a low volume production, experimental item. TAPR is a small, not- for-profit organization of volunteers who have helped facilitate this project because we believe it is a cool thing to have. In order for TAPR to be able to offer this board at all, we must rely on the support of all users in the HPSDR community. The Ozy board is basically a group buy that we have chosen to pre-build because of the difficulty of assembly. TAPR expects that Ozy buyers will seek help on the HPSDR Discussion List for problem resolution.
No support will be available from TAPR staff. You will be expected to join the HPSDR Discussion List and participate in the group discussions of any problems and their solutions. Firmware and software will be available for download from the HPSDR website. Due to the difficulty of packaging the parts and ICs individually, no complete kits of parts can be offered.
Assembled and Tested
Sorry, Ozy A&T is no longer available
The price for the Ozy PCB Only is:
$ 29 US for members of TAPR
$ 32 US for non-members+ shipping/handling if applicable.
Shipping and Handling
Shipping and Handling within the US will be by USPS Priority Mail.
International shipping costs are calculated as closely as possible. If the actual cost exceeds the estimate by more than $10.00, TAPR will contact you to get approval for the additional funds. TAPR uses insured Priority Mail International, unless the purchaser requires something else.
