National Instruments 779460-01 Software-Defined Radio/ Reconfigurable IF Transceiver

Part Number 779460-01 is the identifying part number for the National Instruments PCI-5640R Software-Defined Radio/ Reconfigurable IF Transceiver. The 779460-01 features 2 analog input channels with an ADC having a resolution of 14 bits. The maximum sampling rate is 100 MSamples/second while the maximum bandwidth is 20 MHz. The device also has 2 analog output channels having the same resolution as the analog inputs. However, the maximum update rate at the output channels is 200 MS/s. Both the analog inputs and the outputs are AC-coupled. 

The 779460-01 also comes with a digital downconverter that has up to 6 channels per ADC and the bandwidth can reach up to 20 MHz using all the six processing channels. On the other hand, there is a digital upconverter with a single channel per DAC. The modulation bandwidth using the NI-5640R driver can reach up to 20 MHz while it can reach up to 40 MHz using the LabVIEW FPGA. 

The 779460-01 offers multiple timebase options. The internal clock has a timebase frequency of 200 MHz divided by N, where N is equal to 1, 2, 4, 8, or 16. External sample clock sources can be connected through CLK IN with the help of an SMB connector. The sample clock range for these sources can range from 30 to 200 MHz. The 779460-01 also features 6 TTL-compatible digital I/O lines. It uses a Xilinx Virtex-II Pro P30 (XC2VP30) having 30816 logic cells, 136 multipliers (18 x 18), and a block RAM of size 2448 Kbits.  The module draws 1.8 A to 3.5 A of current at +3.3 VDC, 2.3 A at +5 VDC, and 200 mA at +12 VDC, equaling a total power of 20 to 25.5 W. 

The 779460-01 is recommended for operation between temperatures of 0 °C to 40 °C with a relative humidity of 10% to 90%. On the other hand, it can be stored between a wider temperature range of –40 °C to 70 °C at a relative humidity of 5% to 95%. The device is intended for indoor use only and within a maximum altitude of 2000 m.
