2.2 Power Requirements

The EVM is equipped with three banana connectors (J_GND, J_AVDD and J_VLD) for easy connection of ground, device power, and laser power, respectively. The device, and therefore, the EVM cannot work in a split-supply configuration.

Both the AVDD and PVDD pins of the device are powered up using the AVDD connector of the EVM, but have separate sets of decoupling capacitors. For proper operation, power the device with the supply between the range of 3V to 5.5V.

The VLD connector connects to the anode of the laser diode. The VLD connector also has a series of capacitor banks to provide a high-frequency current when the laser is pulsing.
