CAEN Nuclear Physics

Package

Desktop module, 154x50x164 mm3 (WxHxD), Weight 680 gr

Analog Input

4 channels (MCX 50 Ohm)
Single-ended
Input range: 2.25 Vpp;
Bandwidth: 40 MHz.
Programmable DAC for Offset Adjust x ch., adjustment range: ±1.125V

Digital Conversion

Resolution: 14 bit; Sampling rate: 10 to 100 MS/s simultaneously on each channel; multi board synchronization

ADC Sampling Clock generation

Three operating modes:
- PLL mode - internal reference (50 MHz loc. oscillator).
- PLL mode - external reference on CLK_IN
- PLL Bypass mode: Ext. clock on CLK_IN drives directly ADC clocks (Freq.: 10 ÷ 100MHz).

Digital I/O

CLK_IN (AMP Modu II):
- AC coupled differential input clock LVDS, ECL, PECL, LVPECL, CML
(single ended NIM/TTL available )
- Jitter<100ppm
TRG_IN (LEMO 50 Ohm, NIM/TTL)
GPI/GPO (LEMO 50 Ohm, NIM/TTL)

Memory Buffer

512K sample/ch Multi Event Buffer
Programmable event size and pre-post trigger.
Divisible into 1 ÷ 1024 buffers.
Readout of Frozen buffer independent from write operations in the active buffer (ADC data storage)

Trigger

Common Trigger
- TRG_IN (External signal)
- Software (from USB or Optical Link)
- Self trigger (Internal threshold auto-trigger)
Daisy chain trigger propagation among boards (using GPO)

Trigger Time Stamp

32bit – 10ns (43s range)

USB interface

USB2.0 compliant
Up to 30 MB/s transfer rate

Multi Modules Synchronization

Allows data alignment and consistency across multiple DT5724 modules:
- CLK_IN allows the synchronization to a common clock source
- GPI ensures Trigger time stamps and start acquisition times alignment

Optical Link

CAEN proprietary protocol, up to 80 MB/s transfer rate,
Daisy chainable: it is possible to connect up to 8/32 ADC modules to a single Optical Link Controller (Mod. A2818/A3818).

Upgrade

Firmware can be upgraded via Optical Link or USB interface

Electrical Power

Voltage range: 12 ± 10% Vdc

Software

General purpose C and LabView Libraries
Demo and Software Tools for Windows and Linux
