Power Supply
Do not power up the EM3090 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. The
minimum interval must exceed 2 seconds.
Ripple Noise
The image sensor is directly fed by the input power of EM3090. To ensure the image quality, a power
supply with low ripple noise is needed.
Acceptable ripple range (peak-to-peak) : ≤50mV (≤30mV recommended).
