78P2352 Demo Board

Please check latest availability status for a specific part variant.


The 78P2352 demo board is designed to facilitate easy evaluation of the 78P2352 Line Interface Unit (LIU) in the electrical (coaxial) domain. The board can be easily configured into different operating modes with the on board configuration headers and dipswitches. On the line side, all the necessary discrete components are included for transmitting and receiving CMI signal on the 75Ω coaxial line.

If needed, all other discrete components can be populated to support the optical line interface.
