Power Supply
Do not power up the EM3296 until it is properly connected. Be sure the power is cut off before connecting
a cable to or disconnecting a 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
Image sensor and decoder chip are directly fed by the input power of EM3296. To ensure the image
quality, a power supply with low ripple noise is needed.
Acceptable ripple range (peak-to-peak) :
≤
50mV (
≤
30mV recommended).
