Power Supply
Do not power up the EM3080 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. This 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 500ms.
The EM3080 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.
The EM3080's start-up time is less than 200ms.
Ripple Noise
Image sensor and decoder chip are directly fed by the input power of EM3080. To ensure the image
quality, a power supply with low ripple noise is needed.
Acceptable ripple range (peak-to-peak) : ≤50mV (≤30mV recommended).
