Power Supply
Do not power up the EM1395-LD 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 500ms.
The EM1395-LD itself does not provide a power switch. Users can switch the engine off by cutting off the
power.
The EM1395-LD's start-up time is less than 200ms.
Ripple Noise
Image sensor and decoder chip are directly fed by the input power of EM1395-LD. To ensure the stable
performance, a power supply with low ripple noise is needed.
Acceptable ripple range (peak-to-peak) : ≤100mV (≤50mV recommended).
