I tested this evalkit with 1.8 V power supply. The Jumper JP2 was connected to VDDI and +1.8 V and the supply to J3 and J4. The supply current was 40 - 50 mA per board. The level of the inputsignals was 0- 1.8 V and everything worked without any problems.
Now I tried to operate this evalkit with 3.3 V power supply. I connected the 3.3 V power supply to JP1 connectors and 1.8 V supply to J3 and J4. The Jumper JP2 is connected to +3.3V and VDDI. Now the supply current increased to 80 mA per board. Both Leds on the deserialiserboard was glowing brighter than with 1.8 V supply. The level of the inputsignals was 0- 3.3 V. It was not possible to transmit any signals.
Do I have to change any settings to operate this kit with 3.3 V?
