efficient channel coding, inc. ECC3100 evaluation board data sheet 05/22/06 ?2006 efficient channel coding, inc. 4 1 overview the ECC3100 evaluation board design provides a pl atform for evaluation and demonstration of the ECC3100 skyphy receiver asic in a dvb-s2 forward link receiver sub-system. the evaluation board provides three analog signal inputs: ? 75 ? rf input to analog devices ad8347 direct conversion quadrature demodulator ? 75 ? rf input to zarlink zl10038 advanced modulation satellite tuner ? baseband i & q analog inputs (direct input to adcs) the evaluation board provides four digital data outputs: ? mpeg-2 ts synchronous parallel interface (spi) ? asi serial output based on a cypress hotlink ii transceiver ? serial bert clock and data output ? nec processor local bus this platform processor is the nec vr5500 w ith vrc5477 companion chip. the processor is supported with 32mb of sdram, 32mb of flash memory and interfaces to ethernet, usb & rs232 serial ports. the processor is running an asic device driver th at provides for the initial configuration of the asic, periodic asic maintenance, and tuning of the analog devices demodulator. the processor is also running an embedded java a pplet that provides the user with a gui for asic configuration and status monitoring. the gui can be accessed by connecting the evaluation board to your local area network and pointing a web browser to the ip address of the board. the evaluation platform contains a single fpga wh ich is currently used to translate the 1.8v signal voltage level out of the adcs to 3.3v fo r the asic. future releases of the fpga image will allow for on-board testing of the asic?s demodulator bypass mode. the picture on the following page shows the eval uation board and its various inputs and outputs. 4 .com u datasheet
