The 2245 LVDS-TTL card is a 4hp EEM module. The 2245 LVDS-TTL card is a 4hp EEM module.
It adds general-purpose digital I/O capabilities to carrier cards such as 1124 Kasli and 1125 Kasli-SoC. It adds general-purpose digital I/O capabilities to carrier cards such as 1124 Kasli and 1125 Kasli-SoC.
Each EEM connection provides eight digital channels each. Each card provides sixteen digital channels each, controlled through 2 EEM connectors.
Each RJ45 connector exposes four digital channels. Each EEM connector controls eight channels independently.
Single EEM operation is possible.
Each RJ45 connector exposes four digital channels in the LVDS format.
The direction (input or output) of each channel can be selected using DIP switches. The direction (input or output) of each channel can be selected using DIP switches.
Outputs are intended to drive 100\textOmega~loads, inputs are 100\textOmega~terminated. Outputs are intended to drive 100\textOmega~loads, inputs are 100\textOmega~terminated.
This card can achieve higher speed and lower jitter than the isolated 2118/2128 BNC/SMA-TTL cards. This card can achieve higher speed and lower jitter than the isolated 2118/2128 BNC/SMA-TTL cards.
