The CAEN Mod. V1740D is a Waveform Digitizer, in VME64 form factor, housing a 64 Input Channel 12 bit 62.5 MS/s Flash ADC, designed for waveform recording and supporting advanced algorithms for online digital pulse processing (DPP). The Digitizer is well suited for mid-slow signals generally coming from inorganic scintillators coupled with PMTs, gaseous detectors, and others.

The module features front panel Clock Input/Output and a PLL for clock synthesis and distribution from internal/external references. The event acquisition takes place upon the trigger arrival, in triggered mode for the waveform recording firmware (global trigger), while in streaming readout mode for the DPP firmware (independent trigger). According to the firmware, it is possible to record only waves or waves and physical quantities (Energy and Time). Basically, the trigger source can be either external via the front panel connectors (differential and single-ended), or by software command, or it can be locally generated thenks to self-trigger capability.

Due to the high input density, In the trigger domain, the inputs of the V1740D 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 V1740D is optimized for 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 V1740D boards.

The full communication with the V1740D is possible either via the VMEbus or Optical Link interface. The VME interface allows for transfer rates up to 60 MB/s by using CAEN Bridges (V3718/V4718). 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).

TRIGGER AND EVENT ACQUISITION

Triggered Mode

Trigger Sources

Trigger Timestamp – Waveform Rec. firmware

All the channels fire simultaneously upon a global trigger generated by the Central Logic Unit receiving the trigger source signals. In the trigger domain, the inputs of the V1740D are managed as 8‐channel groups.

Software by register writing
External upon the leading edge of The TRG-IN signal (TTL/NIM)
Local (self-trigger) upon the channel discriminator with programmable threshold

Resolution: 16 ns
Counter range: 31 bits (default); extendable to 48-bit by firmware
Full-scale range: ~ 17 s @31-bit

Streaming Readout Mode

Each 8-channel group autonomously identifies the ROI and uses the local trigger to get events independently on the other groups; validation logics can be configured for correlated acquisition (coincidence/anticoincidence).

Trigger Timestamp – DPP firmware

DPP-QDC:

Resolution: 16 ns
Counter Range: 32 bits (default); extendable to 48 -bit by firmware, to 64-bit by software
Full-scale range: ~ 68 s @32-bit

SYNCHRONIZATION

Clock Generation

CLK-IN/CLK-OUT 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
2.54mm 3-pin AMPMODU Mod II male connector
CLK-IN: AC-coupled LVDS, ECL, PECL, LVPECL, CML (Zdiff = 100 Ω)
CLK-OUT: LVDS

Clock Synchronization

Default 50MHz frequency distributed by:

Fan-in into CLK-IN (DT4700)
CLK-IN/CLK-OUT Daisy chain with sw programmable CLK-OUT delay shift

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

Data Synchronization

Programmable Busy/Veto logic on differential LVDS I/O, or single-ended NIM/TTL I/O for event building.

Run Synchronization (Acquisition Start/Stop)

Optionally, by Daisy chain or fan-in propagation through differential LVDS I/O, or single-ended NIM/TTL I/O.

Trigger Distribution

TRG-IN/TRG-OUT NIM/TTL LEMO I/O (global trigger) or LVDS I/O (global or local trigger).
