Power Supply
Do not power up the EM3080-W V2 until it is properly connected. Be sure the power is cut off before connecting a flexible
cable to or disconnecting a flexible cable from the host interface connector. Hot-plugging could damage the engine.
Unstable power supply or sharp voltage drops or unreasonably short interval between power-ons may lead to unstable
performance of the engine. Do not resupply the power immediately after cutting it off. It is advised that the minimum interval
should exceed 500ms.
The EM3080-W V2 itself does not provide a power switch. Users can switch the engine off by cutting off the power.
Switching it on and off frequently will not shorten the service life of the EM3080-W V2.
The EM3080-W V2's start-up time is less than 300ms.
Ripple Noise
Image sensor and decoder chip are directly fed by the input power of EM3080-W V2. To ensure the image quality, a power
supply with low ripple noise is needed.
Acceptable ripple range (peak-to-peak) : ≤50mV (≤30mV recommended).
