User I/O Xrm Io146 Front Panel Variant - Rev2.0 - Alpha Data ADM-XRC-II Pro Hardware Manual

10 User I/O XRM IO146 Front Panel Variant – Rev2.0
There are 146 I/O signals available on the front panel connector and these can be used individually or in pairs.
All of these pins are compatible with 2.5V and 3.3V signaling (dependant on IO voltage setting on JP1). Care
must be taken when using these signal pins not to exceed the maximum ratings for the V2PRO device.
Each pair of I/O signals is routed as shown below.
The default manufacturing option is Rs=0R and Rt not fitted. Other options are available. Rs can be used to
provide series damping in point to point applications but for LVDS is 0R. Rt is required for LVDS inputs to
provide the termination voltage from the line current.
