XRM2-ADC-S11B - RF/IF Signal Sampling



  • RF/IF Signal Sampling
  • High-speed Analog signal Sampling

Board Features

  • Single 12-bit 2500Msps ADC
  • External Clock Input
  • Alpha Data XRM2 I/O Module


The XRM2-ADC-S11B is an XRM2 I/O Module, providing one Analog to Digital converter with 12-bit resolution and sampling rates up to 2500Msps.

Aimed at IF/RF Signal Sampling, the sampling clock can be sourced from either an external clock source or from a clock generated within the attached FPGA board. A programmable input attenuator can be used to vary the full scale input level over a 15 dB range. An Auxiliary I/O port is provided for use as a trigger input and general purpose signaling. The XRM2 communicates to the FPGA via a JESD204B high speed interface.
