C3 DRK 开发板目标是在开发和测试中帮助算法和信号处理的应用,包括:
- 数字音频、调制/解调的开发;
- 软件定义的无线电
- 高速数据接收和信号处理
- 音频数据接收和信号处理
The system combines a PCI card, an FPGA signal processing card, and a down converting digital radio card. All three cards have connectors allowing them to stack, forming a digital radio system. The kit will operate in standalone mode or the PCI card can be attached to a computer.The standard configuration for the digital radio card is the 75MHz to 150MHz band. The digital radio card is capable of transmitting and receiving RF signals. Filters, Low Noise Amplifiers, and mixers are socket-ed to simplify frequency changes. The card includes a frequency synthesizer LO and mixers for up and down conversion for transmitting and receiving. The card utilizes a 13-bit, 210 million samples per second (MSPS) analog-to-digital converter (ADC), a 14-bit, 400 MSPS digital-to-analog converter (DAC) and an audio codec. The acquired signals are sampled and then digitally processed by the customizable Altera Cyclone III®, 180,000 gate FPGA card. Users may customize the FPGA to implement their own algorithms. The FPGA card comes with a JTAG programming connector and a configuration PROM to retain the FPGA settings. The PCI card provides interfaces for the FPGA card to a computer PCI bus, RS232, and user push buttons. A Digital Radio reference FPGA design example and full documentation are included.Features : Analog Input Path
