The XRM-ADC-S4/3G is an I/O Module which provides a single channel Analog to Digital convertor with 8-bit resolution at sampling rates up to 3GHz.
The XRM is aimed at IF/Baseband Signal Sampling. An external clock source may be used or an internally generated clock can be used to provide the sampling clock. 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.
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.

IF/Baseband Signal Sampling
The XRM-ADC-S4-3G is available for XRM and XRM2 based FPGA products.
30MHz to 1700MHz nominal
Range1: ±410 mV nominal
Range2: ±300 mV nominal
Range selectable via FPGA and ADC serial port: bandwidth limited by input transmission-line transformers. ADC 3dB bandwidth 3GHz.
Note: exceeding the maximum signal limit may result in permanent degredation of converter performance.
50 Ohms, ac coupled
±200mV minimum to +1V maximum
Clock rate of 500MHz to 1700MHz (doubled internally by the ADC)
Note: exceeding the maximum voltage limit may result in permanent degredation of converter performance.
50 Ohms, ac coupled
Source: GTP or User Clock from XRC board.
20MHz to 500MHz - User clock
300MHz to 1500MHz GTP
input 4k7 Ohms, dc coupled
3V3 LVTTL or +5V TTL (factory/user selectable)
Input dc coupled
Note: signals on these connectors must be restricted to 2V5 logic levels else damage may result
Air cooled option
Operating Temperature 0° to +55°C†
Non-Operating(Storage) Temperature -40° to +85°C
Operating Humidity 5% to 95% at 40°C non-condensing
Non-Operating(Storage) Humidity 5% to 95% at 40°C non-condensing
† - It is essential that sufficient air-cooling is provided, if thermal monitoring is provided on board then this should be used to shut the device down if it starts to overheat in order to reduce the possibilty of damaging the devices.
