CAEN Nuclear Physics

Package

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

Analog Input

 32 channels (ERNI SMC Dual Row 68pin) or 16 channels (MCX 50 Ohm)
Single-ended
Input range: 2 Vpp;
Bandwidth: 30 MHz.
Programmable DAC for Offset Adjust x ch., adjustment range: ±1V

Digital Conversion

 Resolution: 12 bit
Sampling rate: up to 65 MS/s simultaneously on each channel
Multi board synchronization

ADC Sampling Clock generation

 Three operating modes:
- PLL mode - internal reference (62.5 MHz loc. oscillator).
- PLL mode - external reference on CLK_IN
- PLL Bypass mode: Ext. clock on CLK_IN drives directly ADC clocks (Freq.: 10 ÷ 65 MHz).

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

 192kSample/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 External TRGIN (NIM or TTL) Command.
Individual channel autotrigger (time over/under threshold)

Trigger Time Stamp

 32bit – 16ns (69s range)

Multi Modules Synchronization

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

USB interface

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

Optical Link
