SLX9 FPGA. After this changes been done, all what is needed is ETI stream from the satellite provider or from ODR Dab. Mux sent by the TCP connection to the board. Just set network parameters, point to the source of ETI stream ip and port, and set RF frequency and amplitude and voliaThere is also modifications page, that describes how to enables SFN operationing by using various GPS   Hardware Description. The software hardware solution looks like this Additional processing done inside FPGA actual modulator schematic Here is the list of used or created IP cores which does the job inside FPGA Pico. Blaze. 6 CPU SPI and AXI4 Stream perpiherals used as arbiter for datastreams and configurator of the DAC. FIFO Buffer for ETI frames. ETI Parser this block parse ETI NI stream and prepare it for modulatorPRBS mix phase reference with data. Convolution adds error correction code to the datastream. Puncturing puncture convoluted data depending on choosed error protection level. Timeinterleave this block interleaves data in time, as described on specification. It needs additional hardware SRAM, which is presented on the board, since its max size may be up to 1.

Spi Serial Flash Programmer Schematic Symbol' title='Spi Serial Flash Programmer Schematic Symbol' />FIR filter, which increases samplerate up to 8. Sampsec and rejects unneeded frequencies. FIFO Buffer for complex samples. Additionally, each FIC data on ETI header is parsed on the fly. This means, that you can switch on the fly from one source to another without rebooting or reconfiguring anything. The limitations are only transmission mode will always be 1 1. Schematic and PCBThe components on board are Wiznet W5. TCPIP job. Maximal bitrate for 5. MHz SPI bus is 1. Mbits. Xilinx XC6. SLX9 FPGA with 8 bit soft cpu and all modulation blocks for DAB mode I.

Micron M2. 5P1. 6 Flash for FPGA bitstream, webpages and saved RF configuration. RFMD SPF5. 18. 9Z or SPF5. Z low noise MMIC amplifier. LDOs, crystals and RF filter. Eagle project files are in source code section. Software and other tools Configuring is based on web interface on port 8. IP Older non SFN enabled firmwares web interfaces sample is here. As additional features, You can turn ONOFF transmission on the fly by pushing Turn OFFON RF frontend, this will switch DAC tofrom sleep mode, so output signal will appear or disappear immediatly. In this case ETI frames processing is still working. Also if you wish to disconnect modulator from the server from which it receiving ETI frames, you can push Turn OFFON ETI socket and connection to the source will be dropped or initiaded again. Usage examples. Modulator needs only network ETI stream, provided by ODR Dab. Mux or satellite ETI stream converted to ETI NI format, below are some examples on how to produce such stream and feed it to modulator Using pre recorded satellite dump file 0,0x. Using old CRC Dabmux application. CRC Dab. Mux L Label. Test A testfile4. S L Label. 1 C O tcp 1. Or You can use minimal configuration file minimal. ETI stream. odr dabmux minimal. Next, go to configuration interface of the board and and set Connection mode to TCP client, Remote IP to your computers IP, where you are running odr dabmux and Remote PORT to 1. After set them, push apply config button and answer Ok for reboot the board. Thats all, you must see that new client connected to the odr dabmux, and boards red led underflow must be turned off, and from now you are on the air. Please note, that Zero. MQ password protection IS NOT SUPPORTED. You need to provide raw TCP for ETI data or Zero. MQ without password. You can discuss this device usage and share your experience in mmbtools group in thread about FPGA DAB Modulator. Measurements. Signal measurements, and process of enchancing of its quality is described on this page. Source codeOld pcb vesrion 1. SFN firmware easydabv.

DO NOT run HTTP based firmware update if You dont have backup ways to revert board to working condition, like SPI flash or JTAG programmer Additiona notes, related to SFN enabled firmware. Non SFN boards also works with newer SFN enabled firmware. So You can use this firmwares on old boards too use 2. MHz as reference clock for old pcbs and 1. MHz for new ones. Its also highly recommended to have additional SPI SRAMs on board for more stabe streaming on high latency networks. Note. 1 if You have no additional SPI SRAM buffers, then accessing to configuration web interface is recommended only when ETI stream source must be turned off, so board is not loaded by modulation task. Note. 2 If some parameters has been changed on web interface and apply config has been pressed and the page status stucks at erasing partition. Otherway You need to do hard reset of the board.
