XRM2-ADC-S4-3G: XRM2 single Analog to Digital converter 8-bit at 3Gsps








XRM2-ADC-S4/3G - IF/Baseband Signal Sampling



Applications

  • IF/Baseband Signal Sampling

Board Features

  • Alpha Data XRM2 I/O Module
  • Single 8-bit 3Gsps ADC
  • External Clock Input
  • Thermal monitoring of the ADCs


Summary

The XRM2-ADC-S4/3G is an XRM2 I/O Module, providing one Analog to Digital converter with 8-bit resolution and sampling rates up to 3Gsps.

Aimed at IF/Baseband Signal Sampling, the sampling clock can be sourced from either an external clock source or from a clock generated within the attached FPGA board. An Auxiliary I/O port is provided for use as a trigger control or for general purpose signaling. An additional two ports are available for use as high-speed interconnect between boards for synchronisation.

The built-in thermal monitor allows the user to check the operating temperature of the ADC. Provided as part of the sample design is the functionality to read the temperature of the device, and software to monitor this and recalibrate the ADC if the thermal drift is sufficient. The software will also shut the ADC down if the device starts to go over the maximum operating temperature.
