Summary

The XRM2-ADC-D10/250 is an XRM2 I/O Module, providing two Analog to Digital converters with 16-bit resolution at sampling rates up to 250Msps.

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 input and general purpose signaling. An additional two ports are available for use as high-speed interconnect between boards for synchronisation.

I/O Interfaces

Interface Type	Qty	Description
ANALOG I/O (Front Panel)
ADC	2	Dual Analog to Digital Converters Resolution: 16-bit Max Clock Rate: 250Msps Impedance: 50Ω Levels: +10dBm Connector: SSMC Note: exceeding the maximum signal limit may result in permanent degradation of converter performance.
DISCRETE I/O (Front Panel)
External clock input	1	External clock input Impedance: 50Ω Levels: -6dBm to +12 dBm (nominal 0 dBm) Connector: SSMC Minimum usable frequency of 40MHz. Note: Exceeding the maximum voltage limit may result in permanent degradation of converter
Auxiliary I/O	2	Auxiliary I/O Impedance: 4k7Ω (DC Coupled) Levels: +3V3 LVTTL (DC coupled) Connector: SSMC Note: Exceeding the maximum voltage limit may result in permanent degradation of converter
DISCRETE I/O (PCB Connector)
Synchronisation I/O	2	Synchronisation I/O Levels: 1V8 Logic (DC coupled) Connector: U.FL - Limited Access in assembled system User configurable as inputs or outputs, signals direct to FPGA pins (Vccfpio). Note: signals on these connectors must be restricted to 1V8 logic otherwise damage may result.
