Analog frontend to Pitaya interface.<\/strong><\/p>\n

To connect the analog module to FPGA it must to generate on dedicated GPIO high signal to send to CNVST command pin. the ADC performs the conversion, and responds with a serial 18bit string of SDOUT-> SDATA, synchronized by the SCLK.<\/em><\/p>\n

In the above image, Piatya to ATCA ISOL Module resistor adapter.<\/p>\n

If you drive more frontend modules is need that the FPGA, for each one, produces a RESET output to enable the ADC, a CNVST output to start the conversion and two LVDS SDIN and SCLK inputs to connect to a 18 bit shift register\u00a0 to be defined in VHDL internally of the FPGA area.<\/em><\/p>\n
