Red Pitaya recently unveiled a new platform featuring the Xilinx Zynq 7020 System-on-Chip to deliver high processing power and greater number of digital I/Os. The STEMlab 125-14 4-Input Starter Kit also provides a GbE LAN port and supports Wi-Fi over USB.

The Xilinx Zynq 7020 FPGA features up to 85K programmable logic cells, 53K LUTs, 106,400 Flip-Flops and 220 DSP slices. Additionally, the Zynq 7020 integrates a Dual-core ARM Cortex-A9 MPCore with CoreSight.

As mentioned earlier, the new STEMlab 124-14 features 4-input channels (±1V/±20V, DC-60MHz) with 125 MS/s sampling rate, 14-bit ADC resolution and 1MΩ impedance. The company also claims that the new RF input performance reduces crosstalk, noise and distortion.

The product announcement also mentioned that “Switching between internal and external clocks has never been easier, thanks to the jumper or control signal located on the extension connector. Additionally, the platform offers the option to lock the internal ADC clock to an external reference clock, which is available via the extension connector.”
