ZN and ZP Pins

ZN (AC5) and ZP (AE5) are the push-pull compensation circuit

 

pins. In Push-Pull mode (selected by the SIP parameter

 

SysPushPull asserted), ZN is tied to VCC_CORE with a resistor

 

that has a resistance matching the impedance Z0 of the

 

transmission line. ZP is tied to VSS with a resistor that has a

 

resistance matching the impedance Z0 of the transmission line.
