1.8 

 PCIe Cable Sideband signals 

 

All Cable sideband signals CPERST#, CPWRON, CPRSNT#, CWAKE# to be connected per the PCIe Cable specification. 

 

Additional isolation of signal CE_PWRON# (card edge power control) shall be provided by a physical switch.   

 

This switch allows user to electrically isolate this signal from the card edge connector. 

 

1.9 

 Block Diagrams (Use Cases)  

Block diagrams for all operating modes. 

 

1.

 

Mode 1: Target Mode: In this mode, the PCI-e cable is attached to an upstream host system, and the card edge supports a 
downstream target device.  Note that the PEX8733’s upstream port is set to 8 by the mode 1 eeprom.  The upstream system 
provides a copy of its SSC, and the on-board buffer provides a copy to the downstream target as well as the PEX8733’s core logic.
