1.1  PZ-TIO Features 

 
The  PZ-TIO  is  designed  as  a  “switchboard”  for  GPIO  signals,  synchronized  by  White 
Rabbit, to route input signals to output signals  and make logical combinations between 
them in FPGA fabric. It has the following features and capabilities: 

 

40+ GPIO connections to PicoZed Zynq SOM 

 

3 SFP interfaces  

 

Supports White Rabbit IP core implementation in PicoZed by providing clocking 
circuitry for 2 SFPs (on daughterboards) 

 

Carries PicoZed Zynq processor with embedded Linux, acting as a standalone PC 
with built-in SD card drive, USB host, 10/100/1000 Ethernet, webserver, etc 

 

Optional 1588 PTP and SyncE clock synchronization for Linux 

 

Open source user access to hardware, software and firmware
