Part Number: DS90UB954-Q1

I am using DS90UB954-Q1. I have connected an FPD III coaxial camera to the RX1 PORT

I am applying 12 V DC to J1

I want to vary the voltage from 0 to 16V that can change the voltage to the camera connected at RX1 PINS.

Is there any way we can change the jumper setting the variable voltage can be provided without any damage to the board.

Hi Balvinder,

There is no jumper option on the EVM board to adjust the output voltage on VPOC_LDO1_9V. You would need to recalculate the value of external resistors R105 and R110 to adjust the output voltage on the POC network.

The calculations for calculating the output voltage for the LM2491x can be found on page 13 of the datasheet here: www.ti.com/.../lm2941.pdf
