描述
The ISL73141SEHF7EV1Z board evaluates the operation of the Renesas ISL73141SEH radiation hardened 14-Bit 1000ksps/750kps SAR ADC. This evaluation board is intended to be used with the RHADC-FMCEV1Z data capture board.
The ISL73141SEH device on the evaluation board supports operation of the ISL73141SEH with AVCC set to either 5V or 3.3V. DVCC can be set to 2.5V or 3.3V, but the default setting is 2.5V. The reference voltage to the ADC can be set to 3.0V or 4.096V. Setting the reference voltage to 4.096V is only valid for the 5V version of the ISL73141SEH. The I/O voltage of the CPLD can be set to 2.5V or 3.3V operation as well, but should be matched to the DVCC setting. The supply voltage for the CPLD is set to 1.8V. The supply voltages to the analog input amplifier circuit is set to +7.5/-4.5V. These voltages are all derived from the ±10V supply inputs to the board.
Specifications
- ±10V power supply inputs
- VITA 57.1 FMC connector for interoperability
- Supports -55°C to +125°C operation
- Supporting components support -40°C to +85°C operation
- Jumper selectable for +5V or +3.3V AVCC operation
- Jumper selectable for +4.096V or +3V VVREF operation
Required Components
To properly operate the ISL73141SEH board and the RHADC-FMCEV1Z board the following is required:
- Low phase noise analog signal source (such as the Rohde-Schwarz SMA100A)
- Low phase noise clock source (such as the clock synthesis on the Rohde-Schwarz SMA100A)
- ±10V DC power supply
- 5V, 3.6A switching power supply (such as the CUI ETSA050360UDC-P5P-SZ supplied with the RHADC-FMCEV1Z data capture board)
- USB 2.0 cable and port on PC
- PC running Windows XP® or greater
- ISL73141SEHEV1Z ADC evaluation board
- RHADC-FMCEV1Z data capture board with iRADAnalyzer GUI Software
(EXE)
NOTE: RHADC-FMCEV1Z board with a bypass option is needed if you already have the RHADC-FMCEV1Z
