SU704

Description

This module consist of 5 channel digital input/output (DIO) and 5 LEDs. Each channel can be set to work under the NIM or TTL standard independently, both of them can drive 50 Ohm impedances. If you use a channel as NIM input a 50 Ohm termination resistor must be connected to avoid reflections, this resistor can be connected through software in the version 1 of the hardware or with the help of a jumper in version 2. For all signals was used LEMO connectors. The maximal work frequency is 100 MHz.

There are three hardware version of this module. The Version 0 is not used any more. The only difference between the version 1 and 2 is that in version 1 the termination resistor can be connected through software and by the version 2 a solder jumper must to be set. The version 2 should have a better noise performance.

The DIO/LED number has been inverted in the FPGA software to match the order of the SU700 module. The LED1 in FPGA connector corresponds the LED5 at the front panel.

Versions differences
