Evaluates: MAX11270 MAX1127X Family Evaluation Kit General Description Features and Benefits The evaluation kit (EV kit) demonstrates the MAX1127X High-Speed USB, FMC Connector, and PMOD family of 24-bit, 64ksps delta-sigma ADCs with integrated Connector PGA. The EV kit includes a graphical user interface (GUI) 5MHz SPI Interface that provides communication from the target device to the Various Sample Sizes and Sample Rates PC. The EV kit can operate in multiple modes: Collects Up to 1 Million Samples (with FPGA Platform) 1) Standalone Mode: In Standalone mode, the EV Time Domain, Frequency Domain, and Histogram kit is connected to the PC through a USB cable and performs a subset of the complete EV kit functions Plotting with limitation for sample rate and size. Save Plots as jpg, bmp or csv 2) FPGA Mode: In FPGA mode, the EV kit is con- Sync In and Sync Out for Coherent Sampling nected to an Avnet ZedBoard through a low-pin- (with FPGA Platform) count FMC connector. ZedBoard features a Xilinx On-Board DAC (MAX542) for DC Signal-Level Zynq -7000 SoC that connects to the PC through an Generation Ethernet port, which allows the GUI to perform differ- On-Board Voltage Reference (MAX6126) ent operations with full control over mezzanine card functions. The EV kit with FPGA platform performs Proven PCB Layout the complete suite of evaluation tests for the target IC Fully Assembled and Tested 3) User-Supplied SPI Mode: In addition to the USB Windows XP-, Windows 7-, and Windows and FMC interfaces, the EV kit provides two 12-pin 8.1-Compatible Software PMOD-style headers for user-supplied SPI interface, Savable ADC Configurations to connect the signals for RDYB, SCLK, DIN, DOUT, and CSB. The EV kit includes Windows XP -, Windows 7 and Windows 8.1-compatible software to exercise the features of the IC. The EV kit GUI allows different sample sizes, adjustable sampling rates, on-board or external reference options, and graphing software that includes the FFT and histogram of the sampled signals with the ability to save Ordering Information appears at end of data sheet. plots in .jpg or .csv formats. The ZedBoard board accepts a +12V AC-DC wall adapter. The EV kit can be powered by the ZedBoard or by a local 12V supply. The EV kit has on-board transformers and digital isolators to separate the IC from the ZedBoard/ on-board processor. The MAX11270 EV kit comes installed with a MAX11270EUG+ in a 24-pin TSSOP package.
