Hi All,

 
I'd like to know a following point about ADN2847 application circuit.

 
According to Figure 15 in the datasheet of ADN2847(RevB), a laser with common PD-cathode and LD-anode is used for this circuit.

 
If a laser with common PD-anode and LD-cathode is used, how to change the circuit?

 
Could you tell me about this?

 
Regards,

 
Taiki
