Jumper Name Default Function
P6
VDDH Soldered VDDH Supply.
P13
VSSH Soldered VSSH Supply.
P8
AVDD +5VA
AVDD Supply. Selection of +5 V A, analog supply from the CED board or +5 V from U3.
P10
–
Soldered VIO Supply. This solder pad can be used to power the FPGA VIO and ADAS3023 VIO together.
P11
–
Soldered FPGA VIO Supply. Supplied from U8, 3.3 V, dedicated digital supply.
P12
VIO
Open
VIO Supply. Selection of 2.5 V (2V5), 3.3 V (3V3), or DVDD (5V). Note that the ADAS3023 digital outputs are set to
this level and are directly wired to the FPGA, U6, which is 3.3 V max. When using the 5 V setting, the ADAS3023
outputs, SDO and BUSY must be resistively divided using the 0603 pads provided on the evaluation board. For
this reason, P10 is used as the default.
P14
DVDD +5VD
DVDD Supply. Selection of +5 V digital, +5 V D, and +5 V from U3.
P15
VDRV- −5VA
U20 V−/P34 Supply. Selection of −5 V A, analog supply from the CED board or GND.
P33
VDRV+ +5VA
U20 V+/P35 Supply. Selection of +5 V A, analog supply from the CED board or +5 V from U3.
P34
U4 V+ VDRV+ U4 V+ Supply. Selection of VDRV+ or U2.
P35
U4 V− VDRV− U4 V− Supply. Selection of VDRV− or GND.
P22
−15V Soldered −15 V CED Supply.
P23
−5VA Soldered −5 V A (Analog) CED Supply.
P24
+5VA Soldered +5 V A (Analog) CED Supply.
P26
+5VD Soldered +5 V D (Digital) CED Supply.
P30
+15V Soldered +15 V (Analog) CED Supply.
