PL3307 Decoder Integration Guide
PL3307 Electrical Information
Power Supply Requirements
The PL3307 decoder board can be powered from one of three possible sources: Host 3.3 VDC, Host 5 VDC, or
Micro USB 5 VDC. The PL3307 uses an intelligent hardware multiplexer to configure the most efficient power
supply arrangement for the combined PL3307/imager engine system.
Figure 2-2
shows a block diagram of the
supply multiplexer.
Figure 2-2
PL3307 Power Supply Multiplexer
The multiplexers are low resistance switches that automatically select between A and B inputs. If both inputs
are present (e.g., Host 5 VDC and Host 3.3 VDC) the A input takes precedence.
This arrangement allows powering the PL3307 using 3.3 V, 5 V, or combined supply voltages that offer
improved efficiency for the overall system due to the different supplies that the PL3307 decoder and imager
engine require internally.

NOTE
Host 5 VDC and Micro USB 5 VDC can not be applied simultaneously to the PL3300 input as these lines
are tied together internally.
