PC722 Kintex-7™

Dual 8-bit 1.25 Gsps A/D
Dual 14-bit 5.6 Gsps D/A

  • Description

      The PC722 is a high-performance, half-size PCI Express card with I/O capabilities designed to address advanced data acquisition and Digital Signal Processing (DSP) requirements. The card is a variant of 4DSP's widely adopted PC720 Kintex-7 FPGA carrier card with 1GB of DDR3 SDRAM. The PC722 is an excellent choice for high-performance applications, such as software-defined radio, that require large band analog signal digitization or generation through the use of accelerated frequency-domain algorithms. The analog signal inputs for the PC722 are digitized by a dual-channel multi-mode A/D that provides two 8-bit ADC channels that enable simultaneous sampling of one or two channels with a maximum sample rate of 1.25 GSPS (2-channel mode) or 2.5 GSPS (1-channel mode). In addition, the PC722 offers flexible control of clock source, sampling frequency, and calibration through the I2C serial communication bus. The A/D design is based on the E2V Quad A/D EV8AQ160 chipset with DDR LVDS outputs. Analog Signal outputs from the PC722 are available from a dual-channel, very wide band DAC. The two 14-bit D/A channels operate at 5.6Gsps (2.8Gsps direct RF synthesis). The D/A design is based on the Analog Devices AD9129 single channel 14-bit 5.6Gsps digital-to-analog converter. The analog signals are AC-coupled, connecting to MMCX or SSMC coaxial connectors on the front panel. The PC722 is equipped with power supply and temperature monitoring and offers several power-down modes to switch off unused functions for both A/D and D/A.
