The CAEN Mod. DT5740 is a Waveform Digitizer, in Desktop form factor, housing 32 Input Channel 12 bit 62.5 MS/s Flash ADC, designed for waveform recording. The Digitizer is well suited for mid-slow signals generally coming from inorganic scintillators coupled with PMTs, gaseous detectors, and others. 32 input channels are available on ERNI SMC connectors, while 16 channels are optionally available also on MCX connectors.

The module features front panel Clock Input and a PLL for clock synthesis from internal/external references. The event acquisition takes place upon the trigger arrival in triggered mode for the waveform recording firmware (global trigger). Basically, the trigger source can be either external via the front panel connectors (single-ended), or by software command, or it can be locally generated thanks to self-trigger capability.

Due to the high input density, In the trigger domain, the inputs of the DT5740 are managed as 8‐channel groups. The acquisition digital memory is a SRAM Multi-Event Buffer of 192 kS/ch divisible into 1 ÷ 1024 buffers of programmable size.

The DT5740 supports multi-board system building, allowing all ADCs to be synchronized to a common clock source and ensuring Trigger time stamps alignment. Once synchronized, all data will be aligned and coherent across multiple DT5740 boards.

The full communication with the DT5740 is possible either via the USB or Optical Link interface. The USB 2.0 interface allows for transfer rates up to 30 MB/s . The Optical Link supports transfer rate of 80 MB/s and offers Daisy chain capability; therefore, it is possible to connect up to 8/32 ADC modules to a single Optical Link Controller (Mod. A4818/A5818).

Software available (Windows and Linux):
CAEN provides drivers for all the different types of physical communication channels, a set of C, Python, and LabView libraries (CAENComm and CAENDigitizer), demo applications and utilities:

CAEN Toolbox: tool that allows the user to update the firmware of the digitizers, change the PLL settings, load, when requested, the license for the pay firmware and other utilities.

Waveform Recording Firmware compliant:

CAEN WaveDump: software console application that can be used to configure and readout event data from any model of the CAEN digitizer family and save the data into a memory buffer allocated for this purpose.
WaveDump2: Open source GUI-based application for the single and multi-board management of Digitizer 2.0 and 1.0 Series running the Waveform Recording / Scope firmware.

SYNCHRONIZATION

Clock Generation

CLK-IN Connector

By default, the Digitizer’s main clocks are generated upon a 50MHz reference frequency that can optionally be internal (50MHz local Oscillator) or external (CLK-IN). Onboard programmable PLL allows locking to different external frequencies.

Reference clock differential signal

Default 50MHz frequency distributed by:

Fan-in into CLK-IN (DT4700)

PLL programming files for supported custom frequencies can be generated and loaded by the CAEN Toolbox software.

Data Synchronization

Programmable Busy/Veto logic on single-ended NIM/TTL I/O for event building (external hardware required).
