7. Recommended Interface Circuit (AC Coupling) 
 
 
 
 
 
 
 
 
 
C1/2/3          = 4.7 uF                         
 
C4/5/6/7    = 100 nF 
L1/2                = 1 uH                           
R1/2                =68 
Ω (If C4/5=0, then R1/2 =82 Ω, it is for DC-coupled.) 
R3/4                =180 
Ω (If C4/5=0, then R3/4 =130 Ω, it is for DC-coupled.)
 
R7/8                =270 
Ω     
WR5/6/9/10/11/12        Depend on SerDes chip used
 
R13                  = 510 
Ω         
 
  Value of R5/6/9/10/11/12 may vary as long as proper 50 
Ω termination or differential 100 Ω is 
provided. For good EMI performance, the power supply filter is required. Use shorter tracks from the 
inductor L1/2 to the module VccTx/VccRx .
