Chapter 3 Electrical Specifications 

Power Supply 

Do not power up the EM3096 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 

Image  sensor  and  decoder  chip  are  directly  fed  by  the  input  power  of  EM3096.  To  ensure  the  image 

quality, a power supply with low ripple noise is needed.   

Acceptable ripple range (peak-to-peak) : 

≤

50mV (

≤

30mV recommended).
